The Basics of GaN Charger Technology | ZONSAN

2022-12-03
GaN, also known as gallium nitride, is the latest generation of semiconductor material with great potential for development and application. GaN is 3 times larger than silicon in terms of band width, 10 times higher in terms of breakdown field strength, 3 times higher in terms of saturation electron migration rate, and 2 times higher in terms of thermal conductivity. Some of the advantages of these performance improvements are that GaN is more suitable for high power and high frequency power devices than silicon, while still being smaller and having greater power density. A more intuitive example is that if all electrical appliances are replaced with GaN, the overall electricity consumption will be reduced by 20%.


History of semiconductor materials


1. The first generation of semiconductor materials
Si, Ge based elemental semiconductors, small and medium power microelectronic devices
2. Second generation semiconductor materials
GaAs, InP and other compound semiconductors, LED, LD and other optoelectronic devices
3. Third generation semiconductor materials
GaN, SiC and other broadband semiconductors, high-power microelectronic, optoelectronic and microwave devices

Features of GaN

1. High forbidden band width, can cover red, yellow, green, blue, violet and ultraviolet spectral range
2. High frequency characteristics, can reach 300GHz (silicon is 10G, GaAs is 80G)
3. High temperature characteristics, normal operation at 300°C (very suitable for aerospace, military and other high temperature environments)
4. High saturation speed of electron drift, small dielectric constant, good thermal conductivity
5. Acid, alkali and corrosion resistance (can be used in harsh environments)
6. High voltage characteristics (shock resistant, high reliability)
7. High power (high power devices)

GaN applications

1. Wall charger, desktop charger
2. RF components
3. GaN HEMT Chip, HEMT MMIC
4. Active phased radar
5. Broadband communication
6. Microwave power devices
