Research Group Data Archive, 1985-2018
Included here are two parallel archives, one of raw spectral DATA and the other of spectral ANALYSIS. There is a small number of other spectra, such as of positron lifetimes, x-ray diffractograms, “DATA” contains raw ...
Photo-Induced Deformations of Nematic Liquid Crystal Elastomers
This dissertation is concerned with studying liquid crystal elastomers (LCEs), and investigating applications. The mechanisms that govern the photo-induced strain in the liquid crystal are studied using a series of experiments ...
Atomic Jump Frequencies in Intermetallic Compounds Studied Using Perturbed Angular Correlation of Gamma Rays
Atomic jump frequencies were determined in a variety of intermetallic compounds through analysis of nuclear relaxation of spectra measured using the nuclear hyperfine technique, perturbed angular correlation (PAC) of gamma ...
Large volume single crystal growth of Cadmium Zinc Telluride with minimal secondary phases for room temperature radiation detector application
Two major aspects of Cadmium Zinc Telluride (CdZnTe) crystal growth for room temperature radiation detection application namely tellurium rich second phase defects and single crystal yield have been addressed. Various ...
MULTI-BASELINE SEARCHES FOR STOCHASTIC SOURCES AND BLACK HOLE RINGDOWN SIGNALS IN LIGO-VIRGO DATA
We present a framework for the detection of stochastic gravitational-wave (GW) backgrounds, from cosmological and astrophysical sources, using radiometry with a network of gravitational-wave interferometers. The search ...
INVESTIGATING [X/FE], IMF AND COMPOSITENESS IN INTEGRATED MODELS
This dissertation explores several existing challenges of evolutionarystellar population synthesis models in integrated light:age-metallicity degeneracy, initial mass function (IMF), elementalabundances, and compositeness. ...
EXCIMER LASER INTERACTION WITH ZINC OXIDE
When single crystal ZnO is exposed to 193-nm laser photons in vacuum at fluences below 100 mJ/cm
Investigations of ternary alloys using perturbed angular correlations
The intended goal of this research was to investigate interactions between solute atoms in intermetallics using a nuclear probe method, Perturbed Angular Correlation (PAC) of gamma rays. The PAC probe, radioactive 111In, ...
Nuclear relaxation in CoGa3 lattice structures
Perturbed Angular Correlation (PAC) Spectroscopy is a method utilized to study hyperfine interactions within solids by observing the gamma rays emitted by the nuclear decay of probe atoms that have been artificially infused ...
