固态等离子体S-PIN二极管仿真设计

摘要

Simulation S-PIN diodes is set up based on semiconductor theory, in order to get the carrier concentration,mobility ratio and optimized structure of diode,in which carrier concentration induced by forward bias on the surface of diodes reaches 1018 cm-3 . This high carrier concentration phenomenon so called solid state plasma phenomena,results in metal-like features of S-PIN diodes. Then the S-PIN diodes array is simulated,in order to confirm metal-like area,which can be used in RF antenna instead of metal.%介绍固态等离子体器件S-PIN二极管的仿真。在半导体理论的基础上建立S-PIN二极管的物理模型,利用软件对S-PIN二极管结构进行仿真计算,研究固态等离子体载流子浓度、载流子迁移率等参数性质,计算出二极管导通状态下的电导率。对二极管结构进行优化设计,使二极管导通情况下载流子浓度能够达到1018 cm-3,导电性能类似金属。这种高密度载流子聚集的现象被称为固态等离子体现象。仿真设计并排级联的S-PIN二极管阵列,得到类似金属导电性的连续固态等离子体区域,能够取代金属材料制备射频微波天线。
