Arsenic-doped silicon detector

Abstract. A new in ared camera (AIR Camera) has been developed at NASA - Ames Rraeaich Center for observations from gronnd-based telercopes. The heart of the camera is a Hu es 58 x 62 pixel Arsenic-doped Silicon detector array that has the spectral sensitivity range to allow observations in both the 10 and 20 micron atmospheric windows. 

Two 256X256-pixel arsenic-doped-silicon (Si As) impurity band conduction (IBC) hybrid detector arrays developed by Hughes Technology Center have been evaluated for space-based astronomy applications. Potential applications include instrumentation on orbiting astronomy platforms such as the Space Infrared Telescope Facility (SIRTF). 

The first demonstration of BIB detector used arsenic-doped silicon (Si As) is the IBC material. A schematic cross-section of a basic Si As BIB detector structure is shown in Figure 1.
