Frequency and Field Strength Materials Characterization with Complementary Split-ring Resonators, Coplanar Waveguides, and the Virtual Ground Method
(University of Missouri -- Kansas City, 2019)
In the radiofrequency bands, measuring the power-dependent complex permittivity
and permeability of materials that undergo metal–insulator transitions is a significant
challenge which is important for defense and ...
Ferroelectric System Dynamics and the Properties of Ferroelectric / Two-Dimensional Electron Gas Heterostructures: a Ginzburg–Landau Study
(University of Missouri -- Kansas City, 2017)
Understanding the electronic response of materials to applied electric fields is an
outstanding goal in solid-state theory. One aspect of this goal is to accurately predict the
electric polarization of certain materials ...
Photoemission Spectroscopy Studies of New Topological Insulator Materials
(2015-08-04)
As the size of a solid shrinks, the ratio of surface area to bulk volume grows and
surface effects become more important. In a world where technologies advance with the
shrinking size of electronic devices, one phase of ...
Design of Instrumentation and Methodologies for Determination of Free Neutron Characteristics
(University of Missouri -- Kansas City, 2017)
Measuring neutron source‐dependent free neutron properties over a large neutron energy range, with human‐portable instrumentation, continues to push the frontier of neutron detection instrumentation design and analysis ...
The Bulk and Interfacial Electronic and Chemical Structure of Amorphous Hydrogenated Boron Carbide
(2013)
The chemical and electronic structure, as related to the surface, interface and bulk of amorphous hydrogenated boron carbide (a-BxC:Hy), is of interest in neutron detection and microelectronics. This dissertation investigates ...
