Numerical Analysis of the Non-cooled Infra-red Sensors based on Different Thermoelectric Wires or Films

Abstract

Calculation and optimization of parameters for thermoelectric sensors of infra-red radiation based on InSb, Bi2Te3, antimony and Bi-Sb alloys were realized. Sensitivity, time constant and noise equivalent power (NEP) of those sensors were determined at different conditions. It was fulfilled the comparative analysis of sensors based on wires or films. Both advantages and disadvantages of corresponding constructions were discussed. The obtained results were compared with experimental data received in Academy of Sciences of Moldova (ASM) and literature data. This comparison confirms a good quality and perspective of studied constructions.
