Optimization of N-type InSb photoconductive detectors

Abstract

The aim of this paper is to study the influence of power dissipation on the performance of n-type InSb photoconductive detectors for 3-5 /spl mu/m atmospheric window. By providing mainly a convective heat transfer among the elements of the device the power dissipation has been increased to 10 W/cm/sup 2/. An improvement in the spectral detectivity is observed. No enhancement in the total noise is remarked.
