Abstract

Bi 2Te 3, recently recognized as a "topological insulator", is proposed to have enhanced electrical and thermoelectric properties due to the topological surface state. In this work, we describe our technique for synthesizing Bi 2Te 3 thin films with the Scotch tape method. We also describe strategies for fabricating samples for transport and thermoelectric measurements. Preliminary data of carrier density and mobility at room temperature was obtained.
