Abstract

The purpose of the study is to determine and characterize, through first-principle calculations, doping impurities that modify the transport properties of electric carriers in the As2Se3 and As2S3 calcogen compounds, in order to maximize their figures of merit, aiming at the use of compounds in thermoelectric applications.
