PbTe thin films with fine grains were successfully fabricated by the gas evaporation method. Thermoelectric properties, i.e., Seebeck coefficient and electrical conductivity, both decreased with decreasing grain size. This was attributed to the decrease in carrier mobility exceeding the increase in carrier concentration with decreasing grain size. It was clarified that the effects of grain boundaries and of oxidation on carrier mobility are considerably large.

N-type Bi2(Te0.95Se0.05)3thermoelectric thin films with thickness 800 nm have been deposited on glass substrates by flash evaporation method at 473 K. The structures, morphology of the thin films were characterized by X-ray diffraction and field emission scanning electron microscope, respectively. Thermoelectric properties of the thin films have been evaluated by measurements of Seebeck coefficient and electrical resistivity at 300 K. Annealing effect on Seebeck coefficient and electrical resistivity of the thin films was examined in the temperature range 373–573 K. When annealed at 473 K for 1 h, Seebeck coefficient and electrical resistivity are –180 μV/K and 2.7 mΩcm, respectively. Thermoelectric power factor is improved to 12 µW/cmK2.
