Photoconductive thin films on the basis of PbSe have been used as functional materials for infrared (IR) detectors. High quality PbSe thin films were grown on glass substrates by chemical bath deposition (CBD) yielding a peak detectivity of 2.8 × 1010 cm Hz1/2 W−1 at room temperature. The photoconductive sensor function is established by a sensitization process by annealing PbSe films in oxygen and...
