Sb2Te3 single crystals have been grown by Travelling Heater Method. EDAX was carried out for confirmation of constituent elements. By the measurements of Dielectric constant (k) and dielectric loss (tanδ), we are able to understand various polarization mechanism in the grown crystals such as space charge polarization, orientational polarization of dipoles and atomic polarization of lattice. AC conduction and Dielectric studies were performed at various frequencies ranging from 100 Hz-1 MHz and temperature 303 K-503 K. From, the AC conduction studies, it is confirmed that the mechanism responsible for the conduction process is hopping. The variations of the dielectric constant (k) and loss (tan δ) as a function of frequency at different temperature are observed and the results were discussed. The activation energy has been evaluated from the dependence of temperature on conductance. TCC and TCP are also calculated from the temperature dependence of capacitance.
