Abstract

Current-voltage (I-V) and R0A curves and spectral response as a function of bias voltage and temperature of p-n indium gallium arsenide antimonide (In0.14Ga0.86As0.13Sb0.87)/n-GaSb photodiodes are presented. InGaAsSb quaternary alloys with a bandgap energy of about 653 meV were grown using the liquid phase epitaxy technique on top of (100) GaSb substrates. Device structure was fabricated using a process that includes passivation with sodium sulfide, thermal annealing and metallizations. The diode architecture was a back-illuminated (B-I) structure with a ring-shaped metallic contact in the GaSb substrate face. Photodiode spectral response showed good performance in the entire temperature range between 20 K and 300 K.
