Abstract

We report bulk GaInNAs p-i-n photodiodes lattice-matched to GaAs substrates, grown by solid source molecular beam epitaxy with photoresponses out to similar to 1.3 mu m. The as-grown samples were characterized optically, structurally, and electrically. A low background doping concentration in the range of 10(14)-10(15) cm(-3) was obtained in the samples. One of the samples with a 0.5 mu m thick GaInNAs absorbing layer gave a responsivity of 0.11 A/W for a band edge of 1.28 mu m at reverse bias of 2 V.
