Gallium Nitride: Overview This is an inorganic material with the chemical name GaN. It’s a compound made of gallium and nitrogen, and it is a semiconductor that has a large direct energy gap. Since 1990 it is commonly used in the manufacture of light-emitting devices. This compound has high hardness and a similar structure to wurtzite. Gallium Nitride has an energy gap of about 3.4 electron-volts. This can be useful in high-speed, high-power optoelectronic devices. Gallium nitride is used, for instance, in violet lasers and non-linear solid-state semiconductor lasers. The conditions allow for the production of a laser that emits a violet light (405nm).
Gallium Nitride: Properties and Stability
1. Avoid contact with oxidizers, heat and moisture.
2. GaN starts to decompose at 1050degC: 2GaN(s)=2Ga(g)+N2(g). GaN crystals are hexagonal and belong to the wurtzite-type lattice system, according to X ray diffraction.
3. It is known that GaN remains stable even at high temperatures. The vapor pressure of GaN at 1130 degrees is lower than what can be calculated using enthalpy, entropy and temperature. This is due the presence of polymer molecule (GaN)x.
4. Cold or hot water, hydrochloric or nitric acids, sulfuric or nitric acids, or 40% HF are not able to decompose GaN. It is stable with cold concentrated alkali. However, it can dissolve when heated.
Gallium nitride material introduction
GaN is the most recent and hotspot in semiconductor research. It is a semiconductor material used for microelectronics and optoelectronics. Along with semiconductor materials, such as SIC or diamond, it’s known as the successor for the first-generation of Ge and Si. Semiconductor material, second-generation GaAs and InP compound semiconductors materials. It has a large bandgap direct, strong atomic ties, high thermal conduction, good chemical resistance (not easily corroded by acid) and a strong anti-radiation capability. It’s used in high temperature, high power and optoelectronic devices.

What is the gallium nitride charge?
Gallium nitride can be described as the core material for third-generation semiconductors. Comparing gallium nitride with silicon, it has a larger bandgap. Gallium Nitride has a larger bandgap than silicon, and can also withstand higher voltages. With the same volume of both materials, gallium is far more efficient than silicone.
Gallium nitride can be found in a wide range of power management devices. At the application-level, gallium nitride is used to charge faster and in a smaller space.
Users will benefit from faster charging but not more volume. Due to the GaN material’s characteristics, the charger can be made smaller and lighter, and it will also have a significant increase in the heat generated and the efficiency of conversion. Many products like CPUs, charger heads, etc. will have a significant decrease in heating efficiency.

What is the price of gallium-nitride charger?
They are also very easy to use. These chargers are small and have a higher efficiency. They can be used to meet many of the demands of modern life, but are expensive.
According to current market prices, the 120w GaN notebook charger costs about 300 yuan. That’s twice or three times as much as the standard 120w charger. Comparing the price of the 120W GaN to the 65w GaN, it is approximately three times more expensive. A 120w charger will buy a normal 120w computer power supply plus a GaN 65w charger.
