Abstract :
We report on the first investigation of the optoelectronic behaviour of an MSM diode above a two dimensional electron gas. The photodetector was fabricated in the InP/InGaAs material system on a HEMT layer structure. Optoelectronic measurements on a device with a finger spacing of 4 μm show a FWHM of the pulse response of 1 ps, at a temperature of 40 K and a wavelength of 890 nm
