Abstract

Thermal detectors find a significant niche in the market of modern sensors. Bi2T3 and PbTe semiconductors are effective thermoelectrics and excellent candidates for different applications. In the present work, a technology for fabrication of the thermal detector based on high-efficient p-Bi0.5Sb1.5Te3 and n-PbTe films on thin flexible polyimide substrate has been developed. The preparation of films was performed by a flash evaporation method. The high sensitivity of the devices is obtained as a result of the high Seebeck coefficient and low value of thermal conductivity for thin thermoelectric films. The devices operate in the Johnson-Nyquist noise limit of the thermocouple. The high performance enables fast and sensitive detection of low levels of thermal power and infrared radiation at room temperature.
