低过剩噪声级联倍增雪崩探测器设计
Design of multi-gain-stage avalanche photodiodes with low excess noise
摘要
Abstract
On the basis of deadspace multiplication theory(DSMT) numeric model and modified deadspace multiplication theory (MDSMT)model,the excess noise of multi-gain-stage avalanche photodiodes with different multiplication stage and different carder initial energy was analyzed.The effects on excess noise of different width of impact-ionization multiplication layer,electron-heating layer and different doping of electric field control layer were also studied.At the same time,the results obtained from DSMT model were compared with the results from Van Vliet model and McIntyre model.By adjusting the width of impact-ionization multiplication layer,electron-heating layer and the doping of electric field control layer,a structure relatively optimizing was acquired by DSMT numeric simulation.The excess noise was comparable to the result of Van Vliet model at ks =0.057.关键词
