On the study of atomic and molecular processes affecting Astrophysical Plasma using high-resolution optical and UV spectroscopy
Rydberg Enhanced Recombination (RER), a recombination process related to dielectronic recombination in which electrons are captured into energy states below the ionization threshold, has been theoretically predicted to ...
Equilibrium Calculation with Toroidal Flow in NIMEQ
The focus of this work is to demonstrate the importance of incorporating toroidal rotation in calculating tokamak-like equilibria with axisymmetry. Specifically, this work will focus on showing the impact toroidal flow had ...
Electron dynamics in inner-shell photo-ionization, dielectronic recombination and electron impact excitation
This dissertation includes three main topics: Dynamics of outgoing inner shell photoionized electrons and Auger decay electrons, an investigation into the recently proposed mechanism of below threshold dielectronic ...
The role of atomic excited states in laboratory plasmas and a study in fine structure diagnostics for far infra-red astrophysical observations
This dissertation has a focus on the role of atomic excited states in laboratory and astrophysical plasmas. The emphasis is on systems for which perturbation theory is not expected to produce accurate results. The work ...
First-principles Theoretical Study of Lattice Thermal Conductivity of Crystals and Earth Minerals at High Temperatures and Pressures
The focus of this dissertation is the first-principles calculation of lattice thermal conductivity, a non-equilibrium thermal transport property, for a wide range of solid materials including both ideal crystals and iron ...
Investigation of Point Defects in AlGaN/GaN High Electron Mobility Transistor Heterostructures Grown on Si Wafers
This PhD dissertation focuses on the investigation of surface/interface defects in AlGaN/GaN high electron mobility transistors (HEMTs) on Si wafers for power electronic applications. Recently, significant attention has ...
