摘要
High speed metal-semiconductor-metal photodetectors sensitive at 1-3 txm have been realised on Si substrates. The active layer consists of a strained InGaAs/GaAs superlattice grown by molecular beam epitaxy on GaAs-on-Si. The device exhibits a very fast response at 1-3/mi (FWHM <:35 ps), a reasonable low dark current (2 fiA and 8/zA at 10 and 20 V bias, respectively) and a wavelength dependent internal quantum efficiency of 15-50% at 20 V bias. © 1990, The Institution of Electrical Engineers.
