Abstract
Combinatorial technology is a powerful tool for new material exploration. La1-xCaxVO3composition-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 soluted films in the full composition range (0≤x≤1) as judged from the linear variation of the lattice constants. Growth conditions of LaVO3films were optimized. Good crystallinity of LaVO3film was obtained at 800°C, and the power factor of 0.6 µW/cm K2was achieved. The effects of oxygen content and the substitutions of Ca and Ce ions on TE properties of were also analysed respectively. Large TE properties in vanadium oxide system can be expected with the change of vanadium ion valence from 3+ to 2+. In La1-xCexVO3(0≤x≤1) system, Ce ion takes 3+ although Ce4+is stable in theory.
