Development of The Third Generation of Semiconductors with SiC and GaN as The Mainstay

Abstract

The application and development of semiconductor technology has a very important role in the development of the world's science and technology. The third-generation semiconductors are broadband semiconductors with high thermal conductivity, high breakdown field strength, high saturation electron drift rate and high bonding energy, which are incomparable to the previous two generations of semiconductors. In this paper, we focus on the third-generation semiconductor materials and further study the most mature and widely used SiC and GaN, and introduce the mainstream methods for the preparation of SiC and GaN. The paper also introduces the applications of these two materials in energy, communication, and consumer electronics, taking into account the current development of the industry. Finally, the paper also considers the problems and challenges that still need to be solved in the next stage of the industry's development.
