Abstract: With the advancement of science and technology, traditional semiconductor materials can no longer meet the high frequency and high power demand. Diamond semiconductor has gradually become a research hotspot because of its excellent physical properties, such as high hardness and wide forbidden band. Through the literature review method, this paper discusses the crystal structure and physical properties of diamond semiconductor, such as high hardness, high thermal conductivity, wide bandwidth and other advantages. This paper also describes its preparation methods, including high temperature and high pressure synthesis and chemical vapor deposition, and discusses the current status of the application in the field of power electronics, optoelectronics, etc. The results reveal that the challenges faced by the doping process are complex, with high costs being a significant issue. However, with the development of technology and process optimization, diamond semiconductor is expected to become a hot spot in the research of high-frequency power.
