Mercury cadmium telluride focal plane array developments at Selex ES for astronomy and spectroscopy
This paper reports on the status of advanced infrared detectors exploiting Metal-Organic Vapour Phase Epitaxy (MOVPE) grown HgCdTe on GaAs at Selex ES. MOVPE has the maturity and flexibility to enable 3rd generation devices to be custom engineered to achieve small pixels, higher operating temperature, high sensitivity and tailored spectral response. The MOVPE technology has now been exploited in the latest development of avalanche photodiodes and single photon imaging is reported. In support of this the latest ROICs have been designed to be compatible with APD operation.
