Thermal Conductivity of Novel Thermoelectric and Nanostructured Functional Materials by Time-Domain Thermoreflectance

Abstract

The experimental focus of the research project was the further development of time-domain thermoreflectance (TDTR) as a high-throughput and nearly universal method for the measurement of the thermal conductivity of materials. The scientific focus of this project was on understanding i) the lower-limits to the thermal conductivity of disordered layered crystals, multilayers, and superlattices; and ii) the distribution of heat carrying phonons in conventional semiconductor alloys.
