Silicon Carbide/Aluminum Oxide Field-Effect Transistors
(2020-07-22)
4H-Silicon Carbide is a wide band gap semiconductor with attractive physical properties for high power, high-frequency devices, and electronics that operate under harsh environments that are not accessible to conventional ...
Modeling of Warm Dense Plasmas for the Determination of Transport Properties and Equation of State
(2020-05-14)
We present the results of research studying the properties of dense plasmas using the average atom model. The average atom model is a physically reasonable statistical representation
of an atom in a plasma, and various ...
Global Hybrid Simulation of Kinetic Alfven Waves Associated with Magnetotail Reconnection and Fast Flows
(2020-05-18)
It is believed Alfven waves, and particularly kinetic Alfven waves (KAWs), play an important role in the coupling between the solar wind and the magnetosphere. Although KAWs have been observed in the magnetotail and ...
Filamentation and Formation of Imposed Patterns in Low-Pressure Magnetized Electric Discharges: A Numerical Approach
(2020-08-03)
Presence of strong magnetic fields (B ≥ 1.0 T) in magnetized dusty plasma experiments can result in a variety of phenomena in the background plasma and in the dust cloud. In the background plasma, the magnetic field induces ...
Theoretical modeling combined with experimental spectroscopic measurements for the diagnosis of high-Z erosion and transport applications in plasmas
(2020-12-11)
Understanding plasma-material interaction (PMI) continues to be a challenge for future
fusion reactors. High-Z materials (e.g. tungsten, molybdenum) have emerged as leading
solutions for plasma facing materials. Erosion ...
Probing and Controlling Electron Dynamics at the Attosecond Timescale
(2021-03-12)
A recently established attosecond beamline, for studies controlling and probing
electron dynamics, has been stabilized with attosecond precision. The design and
performance of the active stabilization system is presented. ...
Characterization of Chromium Trihalide based Magnetic Tunnel Junctions via First Principles Calculations
(2021-04-12)
At finite temperatures, free-standing two-dimensional (2D) materials were originally theorized to be thermodynamically unstable, let alone possess magnetization. However, in 2018, the first ferromagnetic 2D semiconductor ...
Imaging Multi-Particle Atomic and Molecular Dynamics in Dissociative Electron Attachment to CF4 and Double Photoionization of NH3 Molecules
(2021-05-18)
The experimental process and scientific study of two molecular interactions is presented. The first experiment consist of the phenomenon of dissociative electron attachment, (DEA), to Carbon Tetrafluoride, CF4, with the ...
Density Limit Disruptions in the Compact Toroidal Hybrid Experiment
(2021-08-03)
Density limit disruptions in toroidal plasma experiments have been an active area of research for decades. Density limit disruptions are plasma terminations that occur as the plasma
density is increased. Plasma disruptions ...
Simulation of Pickup ions - Local Interstellar Medium Interactions in the Outer Heliosphere
(2021-11-29)
The energetic neutral atoms (ENAs) received by Interstellar Boundary Explorer (IBEX) shows a ribbon structure of the ENA source around the heliopause, the plasma boundary of solar system. The reason behind it is still a ...
