Uses in IR Devices

The use of ACRT at SELEX Sensors and Airborne Systems Infrared Ltd also made possible the fabrication of early 2-dimensional arrays of photodiodes with a high degree of uniformity of response. This type of material was also used to demonstrate nonequilibrium detector operation. The quality and costs of epitaxial material are improving continuously but it will be some years yet before bulk-grown material ceases entirely to be produced, at least for long-wavelength photoconductive applications.
