Abstract

Focal plane arrays (FPA) design requirements and the progress made in the development of Schottky-barrier FPAs to provide very large focal planes of high performance are discussed. It is concluded that improvements were made in PtSi, IrSi, and GeSi heterojunction materials. Using material apportionment, the cutoff wavelength can be tailored up to 16 microns to optimize the relationship between satellite-signal and sensor-cooling requirements. At low exposures, sensor readout noise was reduced to 35 rms-electrons, and good charge-transfer efficiencies were demonstrated down to temperatures of 55 K.
