A high-speed ITO-InAlAs-InGaAs Schottky-barrier photodetector


A high-speed and high-sensitivity vertical indium-tin-oxide-InAlAs-InGaAs Schottky barrier photodetector has been designed, fabricated, and characterized. The devices had dark current densities as low as 8.87/spl times/10/sup -5/ A/cm/sup -2/ at an applied bias of 5 V. The responsivity for all the devices tested ranged from 0.55-0.60 A/W at a wavelength of… (More)
