Perturbation Theory for Thin Cladding Layers on Silicon Photonic Systems
(Vanderbilt University. Dept. of Physics and Astronomy, 2011-04)
I develop a perturbation theory for resonant frequency shifts caused by thin
layer of material added to dielectric systems. This development can be used
to effectively model photonic surface-sensing systems, which use ...
Developing High-Brightness Electron Beam Sources for Producing Quantum Degenerate Electron Beams
(Vanderbilt University. Dept. of Physics and Astronomy, 2011-04)
The Pauli Exclusion Principle places a fundamental limit on the brightness
of an electron beam. Developing a cathode which can reach this limit is
useful for achieving maximum operation in current applications of ...
Finite-Element Analysis of Low-Power Laser Heating in Gold::Vanadium Dioxide Nanocomposites
(Vanderbilt University. Dept. of Physics and Astronomy, 2011-04)
Finite element modeling was performed using COMSOL Multiphysics to study the
thermal dynamics of gold::vanadium dioxide (VO$_{2}$) nanocomposites. These
simulations were done to understand the data from transient ...
Real-time real-space density functional theory calculations of electron scattering in materials
(Vanderbilt University. Dept. of Physics and Astronomy, 2012-05-04)
Density functional theory is utilized in real-time,
real-space simulations of LEED measurements and attosecond electron
scattering. For LEED measurements, we find that our simulation results
agree well with experimental ...
