Title: Thermoelectric properties of Bi2Te3 and Sb2Te3 and its bilayer thin films
Authors: Pradyumnan, P P

Keywords: Thin films
Thermoelectric properties
Bilayer thin films
Issue Date: Feb-2010
Publisher: CSIR
Abstract: The Bi2Te3, Sb2Te3 and Bi2Te3-Sb2Te3 bilayer thin films of various thickness have been prepared using thermal evaporation at vacuum. X-ray diffraction method is used for the characterisation of the samples. Electrical studies have been carried out using the standard four probe method and then the activation energies of each film before and after annealing are obtained. Thermoelectric behaviour of each sample is also determined at various temperature regions.
