Negligible surface reactivity of topological insulators Bi2Se3 and Bi2Te3 towards oxygen and water.

Abstract

The long-term stability of functional properties of topological insulator materials is crucial for the operation of future topological insulator based devices. Water and oxygen have been reported to be the main sources of surface deterioration by chemical reactions. In the present work, we investigate the behavior of the topological surface states on Bi2X3… (More)
