摘要

作者利用漂移-扩散(DD)和流体动力学(HD)模型，对高速p-i-n和单行载流子(UTC)光电探测器(pd)中的高场热电子效应进行了分析微观理论和数值模拟。结果表明，现有的DD输运漂移迁移率模型不适用于具有内建场的强非齐次系统。提出了一种新的DD迁移模型。对比分析了DD模型和HD模型的结果，结果表明HD模型能较好地描述亚皮秒短光脉冲激励下的高速等离子体的运行情况。

Theory and Modelling of High-Field Carrier Transport in High-Speed Photodetectors

The authors present analytical microscopic theory and numerical simulation of high-field hot-electron effects in highspeed p-i-n and uni-travelling carrier (UTC) photodetectors (PDs), using both the drift-diffusion (DD) and hydrodynamic (HD) models for steady-state and transient regimes. It is shown that the current models of drift mobility in DD transport are not applicable for strongly inhomogeneous systems with built-in fields. A new DD mobility model is suggested. Comparative analysis of DD and HD modeling results is carried out and it is shown that the HD model adequately describes operation of high-speed PDs excited by short sub-picosecond optical pulses.
