XRD results indicate that the major diffraction peaks of the film match those of Sb2Te3. The film growth is apparently at the ［101］/［012］ orientation and many Te peaks are observed. Hall measurement reveals that all the samples are p-type and the resistivities are low. The electric conductivity of the films approaches that of the bulk metal and the carrier concentration is of 1023 cm-3. Seebeck coefficient measurement shows that the samples have nice thermoelectrical properties and the seebeck coefficients are in the range of 7.8—62 μV/K. Among all, the samples annealed at 200 ℃ for 6 h have the highest seebeck coefficient of about 62 μV/K and the lowest resistivity.
