摘要: Dark current and avalanche gain M on AlAs0.56Sb0.44 (hereafter referred to as AlAsSb) separate absorption multiplication (SAM) photodiodes (APDs) were measured at temperatures ranging from 77 K 300 K. To avoid possible ambiguity in breakdown voltage due edge tunneling current, a phase-sensitive detection method with tightly focused light spot the center of device was employed measure accurately. An extrapolation 1/M zero used deduce voltage, which temperature coefficient Cbd derived. The value 1/4 8 mV/K, obtained for AlAsSb SAM APDs, is much smaller than that commercial Si InGaAs/InP well other APDs literature, demonstrating potential regions improving thermal stability APDs.
