Abstract: It is shown in this paper that the dark current of InGaAs MSM photodetectors can be greatly reduced with the structure of p-InGaAs Schottky barrier enhanccmcnt layer. Theoretical explanation is given and the lowest dark currents with the order of 10-11 A are obtained in our experiments.

Key words: photodetector, barrier enhancement layer
