The Retrospect and Prospect of GaN-Based Schottky Diode

In the 21st century, with the continuous progress of human society and the continuous upgrading of the integrated circuit industry in recent years, the rapid development of modern science and technology makes us have higher and higher requirements for semiconductor products in our life and production. Compared with the first generation and the second generation of semiconductors, the third generation of semiconductors represented by GaN relies on its high electron mobility, bandgap width, electron saturation speed, high-temperature resistance, radiation resistance, and other suitable material properties. It has more and more extensive application prospects in the research field of microwave high-power devices. Today, the introduction of semiconductors in electronics improves the energy efficiency of equipments and modules. Gallium nitride (GaN) - based schottky diodes have broad application prospects in the next generation of schottky diodes due to their excellent performance. However, because of some technical concerns, these materials have not been fully developed. This work briefly summarized some science and technology related to GaN-Based Schottky Diode. A special focus will be put on the advantages and disadvantages of GaN-Based Schottky Diode, discussing some modern improved designs. Finally, possible breakthroughs of GaN-Based Schottky Diode will be summarized.
