ABSTRACT:
A high speed photoconductive detector is disclosed which comprises two interdigital electrically conducting electrodes formed on a photoconductive layer. The device speed and sensitivity are improved by using a double-heterostructure configuration comprising an active layer formed on an isolation layer in turn formed on a supporting substrate. A passivation layer is formed on the active layer. This configuration confines the generated carriers to the active layer. Consequently, current will be induced under optical illumination due to photo-carrier generation. This interdigitated geometry allows for a large device cross-section and small carrier transit distance.
