Characterization of 4H-SiC/High-κ Dielectric Interfaces via First Principles Calculations
(2022-07-28)
For power electronic devices, wide band gap (WBG) semiconductors are most attractive owing to their excellent physical properties, that they can sustain much higher voltages, frequencies, and temperatures than conventional ...
Investigation of the Redistribution of Kinetic Energy in a Microgravity Complex (Dusty) Plasma
(2022-07-28)
In the presence of gravity, the micron-sized charged dust particles in a complex plasma are compressed to thin layers, but under the microgravity conditions of the Plasma Kristall-4 (PK-4) experiment on the International ...
Fabrication and Characterization of High Temperature P-channel 4H-SiC MOSFETs
(2022-10-18)
Power devices are of paramount relevance with the emergence of greener technology to utilize renewable energy sources. Conventional Si devices are reaching their performance limit due to Silicon’s physical limitation of ...
Particle Charge Determination in a Magnetized Dusty Plasma Flow
(2023-05-04)
Dusty plasmas consist of components typically found in a plasma (electrons, ions
and neutral particles) as well as micrometer sized dust particles. The structural and dynamic
properties of a dusty plasma system are ...
Filament Morphology in Highly Magnetized Capacitively Coupled Low Temperature Plasmas
(2023-08-04)
Due to the small charge-to-mass ratio of dust particles, it is often necessary to use large magnetic fields of B ≥ 1 T, in order to observe the influence of magnetic forces in laboratory dusty plasmas. However, when ...
Transport Properties of 2D Heterostructures Determined via First Principles Calculations
(2023-08-03)
Atomically thin, two-dimensional materials have demonstrated their great potentials in nanoelectronics due to their mechanical and optoelectronic properties. With atomic layers free of dangling bonds, these materials possess ...
Transmission-Type Impedance Probes for Use in Complex Plasmas
(2023-12-04)
Impedance probes measure electron density (ne ) and electron temperature (Te) by interpreting frequency-dependent transmission or reflection spectra (S21 or S11) of radiofrequency (RF) signals of low power (10−5 W). This ...
A spectroscopic neutral density diagnostic and exploration of the role of metastable states in fusion and astrophysical plasmas
(2023-12-04)
Understanding the transition region between fully ionized and neutrally dominated plasmas is important to the study of the magnetosphere of the earth, the corona/chromosphere transition regions of the sun, and detached ...
Photodissociation dynamics of vibrationally excited hydrogen molecules examined with reaction microscopy in kinematically complete VUV + NIR experiments
(2023-12-04)
Using the Cold Target Recoil Ion Momentum Spectroscopy (COLTRIMS) technique, we investigated the dissociation of vibrationally excited H₂ and D₂ molecules after two-color vacuum ultraviolet (VUV) + near-infrared (NIR) ...
Equilibrium Molecular Dynamics Study of Phonon Transport Properties at High Temperatures
(2023-12-06)
Thermal conductivity is a material property of great importance in many areas of physics including coat barriers, renewable energy, nano-electronic devices, and geological processes inside the Earth. At the microscopic ...
