Abstract:

The overall research goal is to gain a detailed understanding of thermal transport through multilayered interfaces between dissimilar materials, using a combination of time-domain spectroscopy, physical modeling and materials processing. Specific goals for the overall project include i investigate the structure, thickness and morphology of the copper-diamond interface for various processing conditions ii assess the effect of interfacial morphology on bulk thermal conductivity, using appropriate models iii publish the results of experimental investigations into bulk thermal properties of copper-diamond composites with various interfacial chemistries, including metallic and carbide layers, and iv mimic the observed interface structure on a TDTR specimen by manipulating the various deposition techniques available to us experimentally.
