摘要: 金刚石是超宽禁带半导体的典型代表,理论上具有禁带宽度大、热导率极高、载流子迁移率高等优点,是高频、大功率、高温电子器件的理想材料。实现高效、高稳定的半导体掺杂是金刚石半导体电子器件应用的必然要求。目前,通过采用氢终端/硅终端等表面改性及硼掺杂等方法已经实现了较为优异的金刚石p型掺杂,并且p型器件也不断取得新的突破。但金刚石n型半导体掺杂却一直没有寻找到合适的掺杂剂或材料改性方法,仍然面临着掺杂效率低、激活能高、材料生长困难等问题。本文系统综述了金刚石采用单元素掺杂和多元素共掺杂方法实现n型半导体掺杂的国内外研究进展,并对各种掺杂方案的优势和缺点进行了分析,对金刚石n型掺杂的发展前景进行展望,希望能为解决金刚石n型半导体掺杂难题提供参考。

Abstract: Diamond is a typical representative of ultra-wide bandgap semiconductors. Theoretically, it has the advantages of a large bandgap, extremely high thermal conductivity, and high carrier mobility, making it an ideal material for high-frequency, high-power, and high-temperature electronic devices. Achieving efficient and stable semiconductor doping is an inevitable requirement for the application of diamond semiconductor electronic devices. Currently, through surface modification methods such as hydrogen termination/silicon termination and boron doping, diamond has achieved relatively excellent p-type doping, and p-type devices have also continuously made new breakthroughs. However, suitable dopants or material modification methods for diamond n-type semiconductor doping have not yet been found, and it still faces problems such as low doping efficiency, high activation energy, and difficult material growth. This paper systematically reviews the research progress at home and abroad on achieving n-type semiconductor doping in diamond through single-element doping and multi-element co-doping methods, analyzes the advantages and disadvantages of various doping schemes, and looks forward to the development prospects of diamond n-type doping, hoping to provide a reference for solving the problem of diamond n-type semiconductor doping.

Key words: diamond; n-type semiconductor; single-element doping; co-doping; activation energy
