Overview of Gallium Nitride
It is an inorganic substance with the chemical formula GaN, a compound of nitrogen and gallium, and a direct energy gap semiconductor. It has been commonly used in light-emitting diodes since 1990. The structure of this compound is similar to wurtzite with high hardness. Gallium nitride has a wide energy gap of 3.4 electron volts, which can be used in high-power and high-speed optoelectronic components. For example, gallium nitride can be used in violet laser diodes and can be used in non-linear semiconductor pumped solid-state lasers. Under the conditions, a purple light (405nm) laser is produced.
The properties and stability of gallium nitride
1. Avoid contact with oxides, heat, moisture, and humidity.
2. GaN starts to decompose at 1050°C: 2GaN(s)=2Ga(g)+N2(g). X-ray diffraction has pointed out that GaN crystal belongs to the hexagonal system of wurtzite lattice type.
3. GaN will slowly volatilize when the temperature is 1000℃ in nitrogen or helium, which proves that GaN is stable at higher temperatures. At 1130℃, its vapor pressure is lower than the value calculated from enthalpy and entropy. , This is due to the presence of polymer molecules (GaN) x.
4. GaN is not decomposed by cold or hot water, dilute or concentrated hydrochloric acid, nitric acid and sulfuric acid, or cold 40% HF. It is stable in cold concentrated alkali, but it can be dissolved in alkali when heated.
Gallium nitride material introduction
The research and application of GaN materials is currently the frontier and hotspot of global semiconductor research. It is a new type of semiconductor material for the development of microelectronic devices and optoelectronic devices. Together with semiconductor materials such as SIC and diamond, it is known as the successor to the first generation of Ge and Si. Semiconductor materials, second-generation GaAs, InP compound semiconductor materials and third-generation semiconductor materials. It has a wide direct bandgap, strong atomic bonds, high thermal conductivity, good chemical stability (hardly corroded by any acid) and strong anti-radiation ability. It is used in optoelectronics, high temperature and high power devices and high There are broad prospects in the application of high-frequency microwave devices.

What is a gallium nitride charger? 
Simply put, gallium nitride is known as the third-generation semiconductor core material. Compared with silicon, gallium nitride has a wider bandgap. The wide bandgap also means that gallium nitride can withstand higher voltages and has better conductivity than silicon. In short, with the two materials in the same volume, gallium nitride is much more efficient than silicon.
In many power management products, gallium nitride is a stronger presence. At the application level, using gallium nitride as a charger can achieve faster charging and smaller volume.
For users, the most direct benefit is that it can bring faster charging, but the volume will not increase as a result. Because of the characteristics of the GaN material, if the charger uses GaN gallium nitride as the material, it can not only achieve small size and lightweight; it also has a very significant increase in heat generation and efficiency conversion. Many products, such as CPUs, charging heads, etc., will significantly decrease their heating efficiency.

The price of gallium nitride charger
Gallium nitride chargers are very convenient to use. Not only are they small in size but also have much higher efficiency than ordinary chargers. It can largely meet the needs of modern people, but they are indeed expensive in terms of price.
With reference to the current price on the market, the 120w GaN charger is generally around 300 yuan, which is twice or nearly three times that of the traditional 120w notebook charger, and the size is not too small. Compared with the 65w GaN charger, the price of 120W GaN is about three times that of it. In other words, the price of a 120w GaN charger is enough to buy an ordinary 120w computer charger plus a 65w GaN charger.
