Investigations on Infrared(IR) Sensitive Material for Microbolometer Using Material Selection Approaches

Abstract

In this paper, distinct desirable and potential materials for the IR sensitive material of a microbolometer along with the material performance properties such as Temperature co-efficient of resistance (TCR), Responsivity, Detectivity, Time constant, Thermal conductance and mass are taken into consideration and Ashby's, VlseKriterijumska Optimizacija I Kompromisno Resenje in Serbian (VIKOR) and Technique for order preference by similarity to ideal solution (TOPSIS)approaches are applied to attain the most suitable IR sensitive material. The analysis results propose that atomic layer deposited (ALD) ZnO is the most advisable IR sensitive material for the better performance of the microbolometer.
