Recently, a class of shallow acceptor levels in silicon, called X-levels, have been discovered which are associated with all the Group III A acceptors. The indium related X-level at 0.113eV appears to be ideally suited to match the 8-12μm atmospheric window. This defect has been shown to arise from a substitutional In and C nearest neighbor pair. We have performed a variety of measurements to determine the feasibility of utilizing the In-X defect in a photoconductor. In particular, silicon crystals heavily doped with both indium and carbon have been grown by thermal gradient transport from indium solutions. Annealing studies have been done to determine whether In-X concentrations in excess of 1-1017cm-3 can be produced in reasonable annealing times. Such a concentration would be necessary to produce detectors with adequate quantum efficiency.
