Abstract
AlInAs/InGaAs metal-semiconductor-metal (MSM) photodetectors with a lo w dark current density are fabricated using a surface modification pro cess with phosphine (PH3) plasma. Phosphidization of the AlInAs cap la yer reduces the surface state density and allows formation of high Sch ottky barrier with a tunnel metal-insulator-semiconductor (MIS) struct ure. A dark current density as low as 0.021 pA/mu m(2) at 10 V is obta ined.
