Gallium Nitride: Overview This is an inorganic material with the chemical formula GaN. It’s a combination of nitrogen and galium that acts as a semiconductor with a large direct energy gap. It is widely used since 1990 in 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-power, high-speed optoelectronic component. 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 heat and moisture.
2. GaN starts to decompose at 1050degC: 2GaN(s)=2Ga(g)+N2(g). GaN crystal belongs in the hexagonal system wurtzite-type lattice, as shown by 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 polymer molecule (GaN).
4. Cold or hot water, diluted or concentrated hydrochloric or sulfuric acids, or cold 40% of HF, will not dissolve GaN. It is stable with cold concentrated alkali. However, it can be dissolved by heated alkali.
Gallium nitride material introduction
GaN is the latest semiconductor material to be developed. It is a semiconductor material used for microelectronics and optoelectronics. Along with other semiconductor materials, such as SIC or diamond, this material is often referred to as the successor 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. The wider bandgap means that gallium is nitride has higher conductivity and can withstand greater voltages. With the same volume of both materials, gallium is far more efficient than silicone.
In many power-management products, gallium is more prominent. 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. The heating efficiency will decrease significantly for many products like CPUs, charger heads, etc.

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 is usually around 300 Yuan. That is two or three times more expensive than the standard 120w charger. Comparing the 120W GaN to the 65w GaN, it is roughly three times more expensive. A 120w charger will buy a normal 120w computer power supply plus a GaN 65w charger.
