Advanced SiO2/SiC Interface Passivation
(2012-10-08)
Silicon carbide is a wide band semiconductor with high critical field EC (~ x7 Si) and excellent thermal conductivity (~ x3 Si). These properties make SiC a good candidate for power switching applications. The Baliga figure ...
Evolution of the Earth's Ring Current during Geomagnetic Storms
(2012-08-29)
We examine the evolution of the ring current during the main and early recovery phases of five geomagnetic storms, three driven by co-rotating interaction regions (CIRs) in the solar wind and two driven by interplanetary ...
Three-Dimensional Hybrid Simulation Of Dayside Magnetic Reconnection
(2011-04-27)
With a three dimensional (3-D) global hybrid simulation model, we
investigate magnetopause reconnection and the energy spectra of cusp precipitating ions under different IMF conditions.
First, the magnetic configuration ...
Fabrication and Characterization of Gallium Nitride Based Diodes
(2011-05-06)
This dissertation describes research to the fabrication and characterization of Gallium nitride (GaN) based diodes. GaN is considered to be probably one of the most significant semiconductor material ever discovered ...
3D Reconstruction of Plasma Equilibrium using Magnetic Diagnostics on the Compact Toroidal Hybrid
(2011-12-05)
Equilibrium reconstruction of magnetically confined plasma for fusion energy research uses magnetohydrodynamic (MHD) theory in combination with experimental diagnostic data to accurately model high temperature plasma ...
Imaging Polyatomic Molecules in Three Dimensions Using Molecular Frame Photoelectron Angular Distributions
(2012-05-10)
We demonstrate a method for determining the full three-dimensional molecular frame photoelectron angular distribution in polyatomic molecules using methane as a prototype. Simultaneous double Auger decay and subsequent ...
Thermal Diffusion of Dopants in Silicon Carbide
(2012-07-27)
Despite considerable advancement in SiC material and device technology, there are still vital issues to be resolved such as metallization and doping. In SiC, ohmic contacts require high concentration doping. Commonly used ...
New Atomic Data For Iron-Peak Elements For Use In Astrophysical Modeling
(2013-07-25)
Supernovae (SN) and supernova remnant (SNR) plasmas represent some of the most
extreme and unusual objects in the universe. X-ray spectra of supernova remnant plasmas
are key to understanding the mechanism and dynamics ...
Imaging Electron-Driven Dynamics in Dissociative Electron Attachment to Gas Molecules
(2013-07-19)
The design and construction of a new ion-momentum spectrometer for the study of
electron-molecule interactions at Auburn University (AU) is detailed with emphasis on the
phenomenon of dissociative electron attachment ...
Investigation of Kinetic Physics of Magnetic Reconnection under a Finite Guide Field
(2011-08-08)
Magnetic reconnection, the process by which the magnetic energy is converted into heat and flow energy, is believed to
be a very important process in space and laboratory plasmas. Among various reconnection models, the ...
