Multiphysics Simulation of Nanostructured Semiconductor Devices
This dissertation describes how to utilize multiphysics simulation techniques to develop physical (optics and device) models of nanostructured semiconductor devices. A hierarchy of approaches (ab-initio, continuum, transfer-matrix, finite-difference time-domain) is used to bridge the gaps in computational efficiency and ...
Interacting Quantum Gases of Lithium and Ytterbium
This dissertation describes the development of a scientic apparatus for trapping ultracold quantum gases of atomic lithium and ytterbium, and discusses the studies of interactions between such particles under a range of experimental conditions. The atoms are sequentially magneto-optically trapped and cooled, and subsequently ...
Compton Scattering and Warm Dense Matter Thermometry
The purpose of this dissertation is to consider the level of detail required for proper theoretical description of non-resonant inelastic x-ray scattering (NIXS) experiments from warm dense matter (WDM). These experiments currently provide the primary means of diagnostic thermometry for low-Z elements of interest for inertial ...
Experiments on a strongly correlated material: photoresponse, phase diagram and hydrogen doping of VO2
The metal-insulator transition(MIT) in vanadium dioxide(VO2) has attracted waves of attention after its rst observation by Morin in 1959. There are several reasons for the interest in this material. First, its metal-insulator transition is at an easily accessible temperature which allows investigators to study the eect of ...
Measurement of a solid-state triple point at the metal-insulator transition in vanadium dioxide
The first-ever accurate measurement of a solid-state triple point in vanadium dioxide was made by performing simultaneous optical and transport measurements on a purpose-built nanomechanical strain apparatus that actively controls the length of a single nanobeam with a nanometer precision. The nature of the metal-insulator ...
