Other AbstractElectrochemically deposited n-type Bi-Te alloy thin films were grown on the conducting polyaniline (cPANI) film electrode whose conducting property with heat treatment temperature was investigated. Cyclic voltammetry was used to determine the deposition voltage of Bi-Te; XRD, EDS and SEM were used for structural, morphological and compositional characterization; Thermoelectric transport properties of the electrodeposited Bi-Te thin films at different temperatures were measured before and after the heat treatment to cPANI; Influences of cathodic potential on the microstructures and thermoelectric properties of the as deposited film were also investigated. The results reveal that cPANI can be almost insulated after heat treated at 180 ℃ for 3 h; Deposited Te content reached a maximum of 67.76% when -125 mV was applied and the structures and thermoelectric properties vary; The conductance of the substrate interferes the properties of the as deposited film. The Seebeck coefficient, electric conductivity and power factor of the as deposited film increased by 47.6 μV/K, 6.86×10^4s/m and 14.3×10^-4W/K^2m, respectively when the cPANI is insulative.
