Title: Pressure-induced insulator-to-metal transitions for enhancing thermoelectric power factor in bismuth telluride-based alloys

Abstract

Straining Bi 2-xSb xTe 3-ySe yactivates additional highly degenerate electronic bands near the Fermi level, providing over two-fold enhancement in thermoelectric power factor.
