OLTP Seminar Series

Online Low Temperature Plasma (OLTP) Seminar Series

Because of the pandemic caused by COVID-19, most scientific conferences, workshops, and symposia have been cancelled or postponed. The unfortunate consequence of this is that the low temperature plasma (LTP) community, like many other research communities, is now isolated without the opportunity to meet, network, and learn what’s new in our field. To remedy this situation, a bi-weekly online seminar has been organized. This seminar series, founded by Prof. Mounir Laroussi of Old Dominion University, is meant to fill the gap left open by the lack of scientific meetings and conferences. The seminar organizing committee has selected several outstanding speakers to participate by giving a 25-30 minutes lecture followed by 10-15 minutes discussion. The seminar, held on Tuesdays at 9:00 AM EST via Zoom, is free to access from anywhere in the world.

For more information, and to request the Zoom link and password, please contact Dr. Ana Borras (anaisabel.borras@icmse.csic.es) and Dr. Mohan Sankaran (rmohan@illinois.edu).

The OLTP seminar is sponsored by AIP Publishing and their Plasma Portfolio of Journals: Journal of Applied Physics, Physics of Plasmas, AIP Advances, and Matter and Radiation at Extremes.

    The Psyche spacecraft was launched into space on Oct. 23, 2023 from Kennedy Space Center on a Falcon Heavy Rocket. The launch was the beginning of the spacecraft’s 2.2 billion mile journey to the asteroid 16 Psyche, located in the outer part of the main asteroid belt between the orbits of Mars and Jupiter. The Psyche asteroid is composed of mostly of metal, and possibly is the metal core of a planetesimal whose formation between Mars and Jupiter was interrupted early in the history of the solar system by collisions with other bodies that created the asteroid belt. The Psyche spacecraft is a hybrid, where Maxar, a major provider of communication satellites and now famous for taking photographs from space over Ukraine, fabricated the spacecraft bus based on heritage hardware from its product line, and JPL installed scientific payload, avionics and autonomous flight software for deep space operation. This $900M NASA mission is enabled by solar electric propulsion, which was first flown by HRL and Hughes in 1997. Psyche will be the first spacecraft to use electric Hall thrusters in deep space to rendezvous and orbit the asteroid. A two-year science program will then determine its composition and remanent magnetic field to determine if this unique object really is a planetary core...and what that actually looks like.
  • Integrated Multi-Scale Modeling of Chemistry in Plasma Reactors Video,

    [#s1820, 11 Jun 2024]
    For the synthesis of new materials and the development of next-generation semiconductor devices, it is essential to understand better the chemical processes occurring in the plasma reactors. Both equilibrium and non-equilibrium plasmas are widely used to advance semiconductor manufacturing processes and nanosynthesis, such as plasma-enhanced chemical vapor deposition (PECVD), ion and electron-assisted surface etching, metal-catalytic nanoparticle formation, and high-temperature nanostructure synthesis. The complex chemistry involved cannot be adequately modeled using a single approach or code because integrated studies of the plasma, the gas phase, and plasma surface reactions over long time scales are required. Such integrated modeling requires ab initio quantum chemistry calculations, molecular dynamics simulations, and kinetic and thermodynamic models. These approaches are to be selected based on the complexity of mechanisms involved in the chemical transformations and the conditions in the reactor zones where these transformations occur. Only a combined approach can cover the complex chemistry throughout the entire plasma reactor volume. As an example of such integrated modeling, we have identified the rate-determining processes for high-temperature boron nitride nanotube synthesis [1], low-temperature diamond CVD [2], conversion of natural gas to hydrogen and valuable carbon nanotubes [3], and surface texturing for black silicon production [4].

  • Electron Beam Driven Plasmas and the Pursuit of Precise Control in Materials Processing

    *Joint Session with the International Online Plasma Seminar IOPS*

    Scott Walton, Naval Research Laboratory, Plasma Physics Division, Washington, DC, abstract
    [#s1815, 28 May 2024]
    The advantages of plasma-based materials processing techniques are numerous. The capability to rapidly and uniformly modify large areas (> 103 cm2 ) with high precision is one reason plasmas are widely used in the materials and surface engineering communities. However, with the ever-evolving demand for new materials and single nanometer-scale device dimensions across a variety of applications, some of the limitations of conventional plasma sources are becoming apparent. The lack of process control and excessive ion energies in the development of atomic layer processing strategies are examples. The Naval Research Laboratory (NRL) has developed a processing system based on an electron beam-generated plasma. Unlike conventional discharges produced by electric fields (DC, RF, microwave, etc.), ionization is driven by a high-energy (~ keV) electron beam, an approach that can overcome many of the problems associated with conventional plasma processing systems. Electron beam-generated plasmas are generally characterized by high charged particle densities (1010 - 1012 cm-3 ), low electron temperatures (0.3 - 1.0 eV), and in reactive gas backgrounds, a relatively low radical production rate compared to discharges. These characteristics allow the ability to precisely control the flux of charged and reactive neutrals as well as ion energy at adjacent surfaces. This provides the potential for controllably etching, depositing, and/or engineering the surface chemistry with monolayer precision. An overview of NRL’s research efforts in developing this technology will be presented, with a focus on source development and operation, plasma characterizations, and how the system can be advantageously applied to the processing of select materials. Examples include graphene, where erosion and damage is a major concern and the etching of semiconductor materials, such as Si, SiN and SiO2, where the focus is on etch rates and selectivity at low ion energy. This work is supported by the Naval Research Laboratory base program.
  • Plasma-catalytic CO2/CH4 Conversion into Alcohols Video,
    Li Wang, Dalian Maritime University, China, abstract, slides
    [#s1742, 14 May 2024]
    The direct conversion of CO2/CH4 into high-value alcohols is a highly desirable route for efficiently utilizing these two C1 sources while mitigating greenhouse gas emissions. However, this reaction is considered one of the most challenging research topics since it suffers from the contradiction between thermodynamics and kinetics. Plasma catalysis offers a promising way for CO2/CH4 conversion into high-value oxygenates under mild conditions, eliminating the need for a two-step high-temperature and high-pressure process via syngas. However, the resulting products are extremely complex, containing CO, hydrocarbons and oxygenates (e.g., alcohols, acids, ketones, and aldehydes). For this talk I will discuss different strategies used to regulate the distribution of oxygenates, in particular how to selectively transform CO2/CH4 into alcohols.

  • Laser Diagnostics Advances for the Study of Electric Propulsion Video,
    Azer Yalin,Department of Mechanical Engineering, Colorado State University, Fort Collins, CO, USA , abstract, slides
    [#s1758, 16 Apr 2024]

    The use of electric propulsion (EP) for spacecraft is seeing growing application from both commercial and government providers due in large part to its ability to offer substantial savings in mass and cost compared to traditional chemical rockets. Underlying these developments are basic studies of plasma dynamics for in-space propulsion which represents a rapidly expanding area in the field of low-temperature plasma (LTP). Experimental study of these plasma systems has relied on physical probes as well as laser diagnostics. Recent developments in EP plasma diagnostics have leveraged laser based techniques that can offer highly spatially and temporally resolved measurements. The present talk gives an overview of several recent diagnostic advances that our group has focused on including time-resolved two-photon absorption laser induced fluorescence (TALIF) for neutral propellant dynamics (to address the “breathing mode”), cavity ring-down spectroscopy (CRDS) for eroded/evolved species, and laser Thomson scattering (LTS) for electron density and energy. In each case, I will explain the diagnostic technique and give examples of its application to EP systems. The suite of diagnostics should also be of interest for other areas of experimental LTP research.

    About the Speaker: Dr. Yalin joined the Department of Mechanical Engineering at Colorado State University (CSU) in 2002 and is currently a Full Professor. He received his undergraduate degree in Engineering Physics from Queen’s University, his MA and PhD degrees from the Department of Mechanical and Aerospace Engineering at Princeton University, and held a post-doctoral position at Stanford University. Yalin’s research interests are in the areas of laser diagnostics for plasma, combustion and atmospheric sensing. He is particularly interested in electric propulsion and plasma engineering and has developed several novel laser diagnostics targeted at these areas. At CSU, he serves as the Director of the Center for Laser Sensing and Diagnostics which includes approximately 10 researchers. He is also the Director of the CSU NASA Space Grant program which supports educational initiatives for diverse undergraduate students.

    Dust is everywhere. 99.99% of the matter in the universe is in the plasma state – it’s everywhere, too. What happens when dust and plasma get together? Dr. Matthews’ research is focused on dusty plasmas: tiny pieces of ice and rock a hundred times smaller than the width of a human hair, and their interaction with plasma, the glowing ionized gas that makes up 99% of our universe. She investigates phenomena ranging from how dust in cosmic gas clouds starts to clump together to form new planets (the formation of cosmic dust bunnies) to how these small particles can assemble themselves into incredibly ordered structures like crystals and helical strings reminiscent of the twisted helix of DNA. Understanding the charging and dynamics of dust is vital to understanding our universe as well as exploring our solar system. Numerical modeling of the coupled charging and transport processes allows exploration of environments which can’t be easily reached. These models must be validated by comparing with experimental measurements. This talk will provide a brief overview of current capabilities of numerical models and their validation against both ground and space-based experiments.

    During the last decade, ultra-powerful (≥500 MW) sub-nanosecond (0.5 ns) high-power microwave (HPM) sources (X- and K-band) were developed, which allow microwave-plasma/gas interaction studies in a nonlinear regime never encountered before. In this talk, we present the results of this research carried out at the Plasma Physics and Pulsed Power Laboratory, Technion – Israel Institute of Technology over the last 5 years. Several new phenomena, such as ionization-induced self-channeling of the HPM pulse [1,2], HPM-driven plasma wakefield excitation [3-5], nonlinear complete absorption of the pulse [6], and its super-luminal propagation [7] were observed by experiments and confirmed by theoretical and numerical studies.
  • Atmospheric pressure plasmas: from materials discovery to device manufacturing (video)
    Davide Mariotti, abstract, slides
    [#s1755, 05 Mar 2024]

    Non-equilibrium plasmas offer unique processing environments to synthesize materials with exotic properties not achievable with other methodologies [1-3]. More specifically, atmospheric pressure non-equilibrium plasmas are attractive for their non-vacuum operation, which can facilitate and reduce the costs of their integration in manufacturing steps [4]. In this contribution, the use of atmospheric pressure plasmas to explore new materials and tailor their properties will be presented, including opportunities offered through defect creation, surface engineering, doping and ‘cluster-doping’ [5-6]. Of fundamental importance to achieve materials with desired properties is also the understanding of the underlying plasma mechanisms and therefore efforts in this direction will also be discussed. Finally, examples of plasma-based device fabrication will be described [7]. For instance, this contribution will include aspects that relate to plasma synthesis of nanofluids for solar-thermal energy conversion, functionalization of catalytic surfaces as well as fabrication of solar cells [4, 5, 8, 9].

    Low temperature plasma (LTP) provides a nonequilibrium reaction field for chemically reactive species without thermal heating. For examples, nitrogen plasma chemical reactions compete between oxidation and reduction and the nitrogen cycle is relevant to redox reactions. In situ functionalization of resources can be achieved using plasma-driven catalysts. Moreover, nitrogen fixation occurs under air and water discharge and can be used as a fertilizer in agriculture. Plasma contacts liquid solutions, and materials are created in them. Plasma-liquid interactions induce some beneficial effects. The gain of pharmaceutical effectiveness has emerged and is called plasma pharmacy. There are no clear advantages and disadvantages of plasma-generated products, together with oxidative or reductive stimuli toward living organisms. However, short-lived species have not been a concern; controlled plasma-driven phenomena can be used as pharmaceutical drugs. All plasma-driven phenomena are categorized as a chain of plasma generation, a chemical reaction network with radical formation, and reactions at the surface and through the boundaries of multiple phases. These hierarchical interactions in plasma processing can be revisited and adapted for plasma life innovations through the evolution of plasma-driven science.
  • An introduction to the electrostatic particle-in-cell method and some applications related to streamer discharges video
    Jannis Teunissen, abstract
    [#s1740, 06 Feb 2024]
    This talk will mostly consist of a general introduction to electrostatic particle-in-cell methods, with a focus on the modeling of low-temperature plasmas. In a particle-in-cell code, the evolution of a large number of particles (such as electrons and/or ions) is tracked by solving their equations of motion. Particle collisions, described by cross sections, are usually handled with a Monte Carlo method. Electrostatic fields are computed at every time step on a numerical mesh with a fast Poisson solver. Particle methods can accurately describe a wide range of physical phenomena and they are relatively simple to implement. Drawbacks are that computational costs are often high and that results can be noisy, due to the use of a finite number of simulation particles. I will discuss several approaches to reduce computational costs: the use of adaptive mesh refinement, the adaptation of particle weights during a simulation, efficient Poisson solvers and parallelization. At the end of the presentation, I will present some examples of particle simulations of streamer discharges.

    Alexey Shashurin, abstract, slides
    [#s1596, 24 Jan 2023]
    Measurements of plasma parameters in small-size plasmas are very challenging as many traditional diagnostic approaches cannot be used. The coherent microwave scattering (CMS) offers a convenient diagnostic solution for such small plasmas. It is based on measurement of the constructive coherent elastic scattering of microwaves off the plasma object. Scattered radiation can be detected and attributed after appropriate system calibration to the certain properties in the plasma object including absolute electron count, electron number density, and electron-gas collisional frequency. Fundamentals of the coherent microwave scattering with an emphasis on Thomson, collisional, and Rayleigh scattering in short, thin unmagnetized plasma media will be considered. Ideality of the CMS technique in the Thomson “free-electron” regime will be reviewed where a detailed knowledge of collisional properties (which are often difficult to accurately characterize) is unnecessary to extract electron number measurement from the scattered signal. Substantially higher sensitivity of the CMS in comparison with the incoherent counterpart in the optical frequency domain (laser Thomson scattering) will be discussed. Several experimental demonstrations of the CMS in collisional and Thomson scattering regimes will be discussed. Applications of the CMS for diagnostics of combustion, electric propulsion, nanosecond repetitively pulsed discharges, photoionization in near- and mid-infrared, and small-size glow discharges enclosed within glass tubes will be considered. Dr. Shashurin is an Associate Professor in the School of Aeronautics and Astronautics at Purdue University. His research is focused on experimental plasma science and engineering with special emphasis on diagnostics and applications of plasmas to electric propulsion, combustion, hypersonics, and biomedical engineering. The research results have been reported in >90 peer-reviewed journal articles, >100 conference proceedings, and 9 patent applications. Dr. Shashurin is Associate Fellow of The American Institute of Aeronautics and Astronautics (AIAA), Senior Member of The Institute of Electrical and Electronics Engineers (IEEE), and the recipient of the Welch International Award for 2008.
