ABSTRACT:
A two color infrared detector (10) is described comprising a heterojunction diode and a metal insulator semiconductor ("MIS") device. The diode comprises first (12) and second (14) semiconductor regions which are operable to generate electron-hole pairs when struck by infrared radiation having first and second wavelengths respectively. The gate (24) of the MIS device is operable to generate a potential well in the first semiconductor region conjunction with an insulator layer (22).
