ABSTRACTRecently, CsBi4Te6 has been reported as a high-performance thermoelectric material for low temperature applications with a higher thermoelectric figure of merit (ZT ∼ 0.8 at 225 Kelvin) than conventional Bi2-xSbzTe3-ySey alloys at the same temperature. First-principle electronic structure calculations within density functional theory performed on this material give an indirect narrow-gap semiconductor. Dispersions of energy bands along different directions in k-space display large anisotropy and multiple conduction band minima close in energy, characteristics of a good thermoelectric material.

Background: Thermoelectric material with high performance and low cost is the basic need of today. Bismuth selenide is a thermoelectric material. A set of bismuth selenide thin films having different stoichiometry ratio varying Bi/Se ratio from 0.123 to 0.309 have been prepared. Objective: Present work deals with the synthesis and characterization of various thin films of bismuth selenide. Thermoe-lectric properties of thin films were also investigated. Aim of this work is to investigate the effect of composition ratio on the structural and thermoelectric properties and to find out the best stoichiometry ratio of bismuth selenide thin films which can be used in application of thermoelectric devices. Method: The set of bismuth selenide thin films having different elemental compositions were prepared by employing thermal evaporation technique. Crystal structure and elemental composition of thin films were investigated by XRD and EDAX respectively. Roughness of films were analysed by AFM. Thermoelectric properties of various thin films were al-so measured. Results: XRD spectrum confirms the formation of phases formed in thin films which slightly matched with standard data. AFM results indicate that surface of films are smooth and nanoparticles are generated on surface. AFM results indicate that the surfaces of annealed thin films are smoother than as-deposited thin films. Seebeck coefficient found negative throughout the temperature rang. Power factor is also calculated by Seebeck coefficient and results reveal effect of com-position ratio on Seebeck coefficient , electrical conductivity and power factor. Thin films having the composition ratio of 0.182 exhibited the highest power factor. Conclusion: This study provides relevant basic information of the thermoelectric property of thin films. As well as pre-sents the effect of compositional variation on thermoelectric measurements. From the application point of view in the thermoelectric devices the best stoichiometric thin films out of four prepared thin films have been presented.
