Instrumentation And Measurement Of Thermoelectric And Structural Properties Of Binary Chalcogenides And Half-Heusler Alloys At Extreme Conditions Using A Paris-Edinburgh Press, Jason Lee Baker
UNLV Theses, Dissertations, Professional Papers, and Capstones
Understanding the high-pressure behavior of transport properties has been a driving force in the study of materials under extreme conditions for well over a century being pioneered by P.W. Bridgman in the early 20th century. Research dedicated to the study of these properties leads to a variety of important applications: exploration of insulator to semi-conductor to metal, structural, and electronic phase transitions, correlation of pressure-induced structural phase transitions and the electronic properties along phase boundaries, identifying electronic topological transitions, testing the validity of theoretical models and providing input parameters for calculations at high-pressure and high-temperature conditions, exploration of sample synthesis …
Synthesis And High-Pressure Structural Studies Of Aux2 (X= Al, Ga, In) Compounds, Jason Lee Baker
Synthesis And High-Pressure Structural Studies Of Aux2 (X= Al, Ga, In) Compounds, Jason Lee Baker
UNLV Theses, Dissertations, Professional Papers, and Capstones
Three intermetallic compounds, AuX2 (X = Al, Ga, In), were synthesized by arc-melting proper stoichiometric ratios of high purity Au, Al, Ga, and In. They were found to be single-phase in the CaF2 type Fm3m crystalline structure. Interest in these particular intermetallic materials is due to intriguing pressure-induced behavior such as electronic topological transitions (ETTs), and structural phase transitions as well as their use in a variety of practical applications such as a solar spectral absorber and in electronic circuitry. In this study, the high-pressure structure of these materials was studied using high resolution synchrotron x-ray diffraction (XRD) …
