Abstract Scope |
In this talk, we will present recent advances in thin film thermoelectrics. Our particular focus will be on the thermoelectric response of SnSe thin films. These films were grown on r-, a-, and c-plane sapphire substrates by pulsed laser deposition technique and several state of the art characterization techniques were used to characterize the samples. Thermal conductivity of the films was measured by 3ω technique at room temperature. It was observed that the planar orientation of the substrate influences the thermoelectric response of the SnSe thin films quite significantly. The SnSe thin films deposited on r-plane exhibited the lowest thermal conductivity; the highest power factor and ZT values of 1.96 μW/cm.K2 and 0.45, respectively at 800 K. These results are very exciting and have a potential to lead to efficient thin films thermoelectric modules in future. |
