About the Charging Black Technology—— GaN

GALLIUM NITRIDE is a new type of semiconductor materials, with super thermal conductivity, and high temperature, acid and Alkali resistance, known in China as the third generation of List of semiconductor materials. Compared to the previous two generations, the third generation semiconductor materials can withstand higher voltage, adapt to higher frequency, achieve higher power density, and has high temperature, corrosion resistance, radiation resistance, band gap width and other characteristics. It can meet the new requirements of modern electronic technology for harsh conditions such as high temperature, high power, high voltage, high frequency and radiation resistance, and has a wide application prospect in the fields of high frequency and high power electronics, microwave and radio frequency, list of semiconductor materials is the most promising material in the field.

However, GaN needs to be made by hand, so the equipment requirement is very strict and the technology is very complex, which leads to very low production capacity. GALLIUM nitride single crystal materials are extremely rare, 2 inches of gallium nitride wafers sold for more than RMB20,000. In this year's In CES2020, 30 manufacturers, including our company, have launched 66 GaN quick-charge products, with OPPO, Xiaomi and other mainstream mobile phone brands, the popularization of GaN chargers, as production capacity brings down costs, gallium nitride chargers and other applications will become commonplace.

Miwon will also vigorously develop quick charger this area to meet the needs of the domestic and foreign markets.
