Tuning thermoelectricity in a Bi2Se3 topological insulator via varied film thickness

We report thermoelectric transport studies on Bi _2 Se _3 topological insulator thin films with varied thickness grown by molecular beam epitaxy. We find that the Seebeck coefficient and thermoelectric power factor decrease systematically with the reduction of film thickness. These experimental obse...
