Li Baogeng, Xu Zhitao, Zhao xianming. Planar InGaAs PIN Photodiode with High Quantum Efficiency Low Dark Current and High Reliability[J]. 1994,(Z1).DOI:
The dependence of quantum efficiency and response time on the parameters of device structure were disussed in the paper in detail
which provided the basis for the device design scheme was also derived. According to the design
and the scheme
the pianar photodiodes were realized with quantum efliciency over 90% and dark current at 100pA level (- 5 V ). MTTF (mean time to failure) of the devices is longer than 3 000 h (180°C ) and 500 h(230°C ) at - 10 V bias
