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 ...
Neutron Response Vectorization and Optimization of Moderating Neutron Spectrometers for Active Interrogation
(University of Missouri–Kansas City, 2015)
The detection of special nuclear material (SNM) is no trivial task; the low activity of isotopes such as 235U and the ease of shielding make their passive detection virtually impossible in the maritime environment. Active ...
Modeling and Design of a Silicon-Based High-Pressure 3HE Replacement Neutron Detector
(University of Missouri–Kansas City, 2015)
3He has stood as a major isotope used for neutron detection for many years. Due to national concerns of a possible 3He shortage, significant effort has been put forth, in the form of 3He alternative research, to push the ...
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 ...
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 ...
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 ...
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 ...
