摘要
The semiconductor alloy system (GeTe)(1-x),(AgSbTe2)(x), known as TAGS, is a family of highly degenerate P-type materials with peak ZT well above room temperature. For instance, when x = 0.15, ZT is about 1.4 at 773 K, but is only similar to0.2 at 300 K with a Seebeck coefficient less than 100 muV/K. We revisit this familiar material and some related alloys with regard to their potential for operation at lower temperatures. We are seeking improved room-teniperature electrical properties and, consequently, improved figure of merit.
