As the dimensions of state-of-the art metal-semiconductor-metal photodetectors (MSMPD's) decrease, effects that are insignificant for relatively large geometries become significant in the optoelectronic performance of submicron MSMPD's. Accurate mode

A detailed study of the performance of monolithically integrated photoreceivers based on metal-semiconductor-metal (MSM) photodetectors (PD's) and HEMT's is undertaken. Two different stacked-layer approaches to integrating MSM-PD's with HEMT's are in
