Abstract :
Metal-Semiconductor-Metal (MSM) photodetectors with thick Ga0.85In0.15N0.011As0.989epilayers were fabricated. With small amount of incorporating nitrogen, thick and dislocation-free GaInNAs/GaAs material for absorption layers can be achieved. Photocurrent spectra show that a responsivity higher than 0.06 A/W at 4V is obtained with a cutoff wavelength of 1.2μm.
