PN junction is considered to be the core of great majority semiconductor devices, also, be caught the general public attention and be taken seriously. This text is to explain and discuss the forms and characteristic of PN-junction. Certainly PN-junction forms the fundamental element of the semiconductor device, among them, the simplest crystal diode is made of PN junction . Therefore, studying the characteristic of PN-junction is to discuss the characteristic of crystal diode in fact. This text passes through the studying to crystal diode to expound on One-way conductivity.Breakdown of Characteristic capacitance characteristics, Temperature characteristics and so on of PN junctionKeywords: Semiconductor Drift Movement Proliferation Free carrier The forms of PN-junction目 录摘 要 iAbstract ii第一章 绪论 11.1 研究动机与目的 11.2 论文内容概述 1第二章 半导体的基础知识 22.1 本征半导体 22.2 杂质半导体 22.3 半导体中的电流 4第三章 PN结 63.1 PN结的形成 63.2 PN结的单向导电性 83.3 PN结的击穿特性 103.4 PN结的电容特性 113.5 PN结的温度特性 13第四章 结论 14致 谢 15参考文献 16 |
