  • Abstract
    Lead telluride detector arrays have been made by diffusing indium into arsenic-doped p-type lead telluride. Planar devices have a resistance-area product R0A ¿ 10 ¿ cm2 at 180 K and a black body detectivity (D* 500 K) ¿ 6×109 cm Hz¿ W¿1 a typical array showing a responsivity variation of ±20%. The temperature variation of R0A is consistent with an abrupt junction model with an Auger-limited lifetime.
