This report discusses work performed during the fourth quarterly period of a PEM for producing p-type, gold-doped germanium infrared detectors, type IR400. Work was concentrated on manufacturing and testing of preproduction samples; compilation of the Inspection and Quality Control Plan; and preparation of processing specifications with device, jig, and fixture drawings. About midway in the period, negotiations were completed for a change of scope of the contract to reduce the ...
Work was performed on a PEM for producing ptype gold-doped germanium infrared detectors, Type IR400. During the third quarter of the contract period, work was concentrated on production, evaluation, and testing of singlecrystal material and on sealing barium fluoride windows to glass. Several germanium ingots of varying resistivities and dopant concentrations were pulled by the zone leveling technique. Wafers were sliced from various zones of these ingots and their parameters ...
The reported work is on a PEM for producing p-type gold-doped germanium infrared detectors, Type Ir400. The report covers the second quar ter of the contract period. The work for the period is divided into three main categories: gold-doped germanium crystal growing, material evaluation and testing, and barium fluoride transmission window sealing to glass. The procedures involved in material and device fabrication and testing are discussed. Evaluation data is included ...
