Abstract

Detection of 1.5 to 2.3-micrometer radiation is important for a number of earth resource and military applications. Hgi_xCdxTe photodiodes have recently been developed which offer substantial improvement in operating temperature for detection of 1.5 to 2.3-micrometer radiation. For example, arrays of Hg1-xCdxTe photodiodes with cutoffs in the 2.0 to 2.3-micrometer spectral range have achieved detectivities of 1.0 x 1012 - 4.0 x 1012 cm Hz1/2/W at an operating temp-erature of 193 K. In this paper we present results on these (Hg,Cd)Te photodiode arrays.
