摘要:
The performance of In0.53Ga0.47As metal-semiconductor-metal photodetectors on Si substrates was investigated, The devices were fabricated by standard technology employing metalorganic vapor-phase epitaxy growth on unpatterned exactly [001]-oriented Si substrates and conventional photolithography. At a bias voltage of 5 V the devices exhibit low dark currents of 10(-6)-10(-7) A, a high responsivity of 0.26 A/W at 1.3 mu m, and a cutoff frequency of 1.5 GHz. A further improvement could be achieved by increasing the bias voltage.
