摘要
To realize high thermoelectric performance, it was tried to control both high electrical conductivity (sigma) and low thermal conductivity (K) for the Sn-doped indium-zinc oxide films prepared by DC magnetron sputtering. The highest power factor was obtained post-annealed at 200 degrees C due to the highest s. However, the highest figure of merit was obtained annealed at 500 degrees C. It could be attributed to both amorphous structure with low K by phonon and the highest Hall mobility. Thermoelectric and electrical properties of the film could be controlled by both heat treatment and Sn doping with high bond enthalpy. (C) 2017 The Japan Society of Applied Physics
