Stoichiometric depositions of the nanowires were achieved via systematic study on compositional change as a function of applied potential. Electrical and thermal transport properties of the nanowires were studied using a custom-designed suspended micro-electro-thermal system. Thermoelectric test modules constructed from pairs of p- and n-types BiTe based nanowire arrays thermocouples were demonstrated to produce a power output of ~ 0.36 nW per a pair of P-N thermocouples at a maximum temperature difference of ~ 50 K.

Introduction The discovery of thermoelectric effect in metal chalcogenides such as Bi2Te3 and its alloys with Sb and Se has led to the idea of solid-state refrigeration and power generation. These materials have potential applications in waste heat recovery, air-conditioning and refrigeration. Factors affecting the performance of a thermoelectric material are: electrical conductivity (σ), thermal conductivity (κ) and Seebeck coefficient (S).
