Synthesis and study of transparent p- and n-type semiconductors and luminescent materials

Creator:: Park, Cheol-Hee
Abstract:: New transparent p- and n-type semiconductors and luminescent materials have been prepared and characterized. Synthesis, structures, optical and electrical properties of new chalcogenide fluoride p-type transparent semiconductors MCuQF (M=Ba, Sr; Q=S, Se, Te) are described. Band-gap tuning and improvement in conductivity through p-type doping are demonstrated in the family. The...

Studies of heavy element multi-nucleon transfer reactions using radioactive decay analysis of the 136Xe + 198Pt reaction at a center of target lab energy of 777 MeV (5.7MeV/A)

Creator:: McCaleb, Kyle M.
Abstract:: Recent experiments have advanced the current understanding of multi-nucleon transfer(MNT) reactions. Within nuclear science, most nuclear reaction experiments consist of a stationary target material, that is then bombarded by a moving projectile. Overall nuclear reactions can be used to produce a desired isotope. In the case of this particular study...

Electrochemical Micro-sensors for Probing Bacterial Metabolic Behavior with Scanning Electrochemical Microscopy

Creator:: Jayathilake, Nadeeshani M.
Abstract:: Dental plaque is one of the well-characterized biofilms in the human body. Oral bacterial species play vital roles in maintaining healthy bacterial homeostasis as well as causing oral infections. Many of the oral diseases are caused by opportunistic pathogens, and therefore, the bacterial metabolic activities become important in dictating their...

Investigating Low-Frequency Vibrations in Condensed Matter Using Time-Resolved Third-Harmonic Generation Spectroscopy

Creator:: Wang, Liang
Abstract:: In this thesis, I present a new method we developed to study low frequency (< 700 cm⁻¹) vibrational dynamics: Time-resolved third-harmonic generation (TRTHG) spectroscopy. Among a variety of vibrational spectroscopy techniques, TRTHG differentiates itself with robustness, versatility, and simplicity. In TRTHG experiment, that involves only two ultrashort laser pulses, the...
