- W2084418680 abstract "Schottky barrier infrared detectors have made significant advances in the past several years. These have occurred on many fronts, and have resulted in focal planes which can image in the staring mode with more than 8000 active elements. Initial experimental results of the early 1970's were done with Palladium Silicide detectors. Images made from this material have a cutoff wavelength of about 3.5 micrometers and can adequately cover the near infrared bands with moderate quantum efficiency. In the mid to late 1970's, it was found that PtSi could be formed into infrared sensing arrays with a cutoff wavelength of about 4.7 micrometers. Unfortunately, the early arrays did not cover the region from 4.7 to 5.2 micrometers and suffered from rather low quantum efficiencies. Improvements in processing have overcome both of these initial difficiencies. In fact, PtSi arrays now have cutoff wavelengths of nearly 6.0 micrometers and moderate quantum efficiencies from 3.0 to 5.0 micrometers. They have been measured to be background limited at f/3 and have fixed pattern fingerprints of less than 0.3%. The minimum resolvable temperature at f/3 is less than 0.3°C. Our latest experiments have concentrated in IrSi detectors. These devices have cutoff wavelengths beyond 9.0 micrometers, and have excellent quantum yields in the 3.0 to 5.0 micro-meter region." @default.
