Combinatorial Synthesis and characterization of Thermoelectric Composition-spread ( La1-xCax)VO3 (0≤x≤1) Films

摘要：

La1-xCaxVO3 composition-spread films were fabricated by combinatorial pulsed laser deposition and their thermoelectric properties were evaluated paralelly by the multi-channel thermoelectric measurement system. Concurrent X-ray analysis verified the formation of solid solution films in the full composition range (0≤x≤1) as judged from the linear variation of the lattice constants. The power factor of 0.6 μW/cm K2 was achieved in LaVO3 film at 800℃.Large thermoelectric properties in vanadium oxide system can be expected with the change of vanadium ion valence from 3+ to 2+.
