Abstract

This work is directed at the fabrication and optical characterization of anisotropic semiconductor composites with improved thermoelectric properties. Specifically, the quest is to dramatically improve the thermoelectric figure-of-merit, ZT, with an emphasis on the effects of "nanoconfinement", and on the crystallographic properties which provide an increase in the electrical-to-thermal conductivity ratio. Current work entails the fabrication of force-oriented nanostructural confinement of Bismuth (Bi) and Bismuth Telluride (Bi/sub 2/Te/sub 3/).
