Preparation of Exfoliated Bi[sub 2]Te[sub 3] Thin Films

Bi2Te3, 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 Bi2Te3 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.
