Abstract
An infrared (IR) detector device comprised of a solid state, radiation ha and high resolution monolithic IR focal plane array for imaging applications. The monolithic IR focal plane array has a heterostructure injection scheme that prevents charge coupled device (CCD) 'well filling' by using a heterojunction barrier between the absorber, or detector layer, and the transfer layer. Injection of signal charge into a CCD multiplexer is controlled by establishing a punch through condition between the absorber layer and the CCD channel. The detector layer and the CCD multiplexer are on different planes of the focal plane array.
