Abstract
We present the high performance of InGaP/GaAs metal-semiconductor-metal photodetectors (MSM-PDs) using copper as the interdigital Schottky electrodes. The devices exhibit ultra-low dark current (70 pA at bias of 10 V) and ultra-fast pulse response (over 9 GHz). The notable dark current characteristic and the absence of trap-induced gain are accredited to the superior properties of InGaP capping layer. The superior performances of InGaP/GaAs MSM-PDs make it promising for data communication.
