Abstract: Herein, the thermoelectric properties of vacuum deposited In2Te3 thin films were investigated by varying the substrate temperature and the thickness of the films. The thermo-electro motive force of the prepared films was found to increase with an increase in the substrate temperature up to 423 K and then decrease at 473 K due to the presence of mixed-phase structure. The maximum thermoelectric power of 220 ?V/K was observed for the films deposited at 423 K substrate temperature, which was found to decrease with increase in thickness. The films deposited at 423 K with 150 nm thickness showed maximum power factor of 27 ?Wm?1K?2 at 450 K. These observations are explained on the basis of structural, morphological and compositional changes. 2017 Elsevier B.V.
