Thermoelectric Properties of P-Type Ga2Te5 Based Compounds
چکیده انگلیسی

P-type Ga2Te5 based compounds with multiphase equilibrium were prepared by spark plasma sintering and their microstructures and thermoelectric properties were evaluated in the temperature range from 319 K to 549 K. Through XRD analysis, we observed the main phase Ga2Te5, a small amount of SnTe and single element Te were observed. Results indicate that the Seebeck coefficients increase and the electrical and thermal conductivities decrease with the increase of the temperature in the entire temperature range. The highest thermoelectric figure of merit ZT of 0.16 can be achieved for Ga2SnTe5 at 549 K due to relatively low thermal conductivity and high thermal conductivity.
