Abstract
Thermoelectric power factor of a material significantly relies on its electrical conductivity, thermal conductivity, and Seebeck coefficient. Herein, an attempt has been made to enhance the thermoelectric power factor of In2Te3 thin films by tuning their Te composition and via Se doping. The optimum Se-doping concentration and Te composition enhanced the power factor of pristine In2Te3 films by 14 and 7.4 times, respectively. The modified chemical composition, structural characteristics, and surface morphological features of In2Te3 films are observed to be pivotal in improving their thermoelectric power factor. Overall, this study offers a facile approach to control the thermoelectric power factor of In2Te3 thin films which is significant for their futuristic applications.
