Abstract
The invention is a bulk-processed thermoelectric material and a method for fabrication. The material measures at least 30 microns in each dimension and has a figure of merit (ZT) greater than 1.0 at any temperature less than 200° C. The material comprises at least two constituents; a host phase and a dispersed second phase. The host phase is a semiconductor or semimetal and the dispersed phase of the bulk-processed material is comprised of a plurality of inclusions. The material has a substantially coherent interface between the host phase and the dispersed phase in at least one crystallographic direction.
