Title: Connecting thermoelectric performance and topological-insulator behavior: Bi 2Te 3 and Bi 2Te 2Se from first principles

Abstract

Thermoelectric performance is of interest for numerous applications such as waste-heat recovery and solid-state energy conversion and will be seen to be closely connected to topological-insulator behavior. In this paper, we here report first-principles transport and defect calculations for Bi 2Te 2Se in relation to Bi 2Te 3. The two compounds are found to contain remarkably different electronic structures in spite of being isostructural and isoelectronic. We also discuss these results in terms of the topological-insulator characteristics of these compounds.
