Bi<sub>2</sub>T<sub>3</sub> and PbTe semiconductors are effective thermoelectrics and excellent candidates for different applications. In the present work, a technology for fabrication of <em>p</em>-Bi<sub>0.5</sub>Sb<sub>1.5</sub>Te<sub>3</sub> and <em>n</em>-PbTe films with the high thermoelectric efficiency on thin flexible polyimide substrate has been developed. The preparation of films was performed by flash evaporation method. The high sensitivity of the devices is due to the high Seebeck coefficient of 200 mV/K and reduction of thermal conductivity of thin thermoelectric film from the bulk value. The devices operate in the Johnson-Nyquist noise limit of the thermocouple. The performance enables fast and sensitive detection of low levels of thermal power and infrared radiation at room temperature.</p>}, number={1}, journal={Physics and Chemistry of Solid State}, author={Kostyuk, O.B. and Dzundza, B.S. and Yavorsky, Ya.S. and Dashevsky, Z.M.}, year={2021}, month={Feb.}, pages={45–52} }
