Радиационные Термоэлементы На Основе Теллурида Висмута, Получаемые Методом Импульсного Лазерного Осаждения

Abstract

Radiation thermopiles are basic structures for sensors used for measuring energy parameters of different radiation with wavelength from 0.1 to 100 mcm. Current work describes features of using p-Bi0.5Sb1.5Te3 and n-Bi2Te2.7Se0.3 thin film thermopiles obtained with pulsed laser deposition method on different substrates. Thermal modeling and experimental research reveal the possibility of achieving responsivity of 1 V/W and time constant of 10 seconds with the use of polyimide substrates and absorption zone of 16 mm in diameter
