Gallium Nitride: Overview
It is an inorganic compound with the chemical name GaN. A mixture of nitrogen and galium it can also be called a direct energy gap semiconductor. This compound has been widely used since 1990 in light-emitting transistors. It has an identical structure to wurtzite and high hardness. Because gallium nitride’s energy gap is large at 3.4 electron volts it can be used to make optoelectronic parts that are high-power or high-speed. Galium nitride is a good choice for violet laser diodes. It can also be used to make non-linear solid-state, semiconductor pumped lasers. The conditions are such that a violet light (405nm laser) can be made.
Gallium nitride’s properties and stability
1. Avoid contact with oxygen, heat, moisture and humidity.
2. GaN starts to decompose at 1050degC: 2GaN(s)=2Ga(g)+N2(g). A X-ray beam diffracted has shown that GaN crystal is a hexagonal type of the wurtzite lattice type.
3. If the temperature of 1000 is reached in nitrogen, or helium (GaN), it will slowly volatilize. This is a sign that GaN remains stable at higher temperatures. The vapor pressure of GaN at 1130 is below the value calculated by enthalpy, entropy. This is because of the presence of polymer molecules, GaN (x).
4. Diluted or concentrated hydrochloric or nitric acids or sulfuric acid will not make GaN decompose. Although it is insoluble in cold concentrated acid, you can dissolve it in alkali by heating.
Gallium nitride material introduction
Global semiconductor research is at the forefront of GaN material research. This new semiconductor material is used in the creation of optoelectronics devices as well as microelectronics devices. This material is known to be the successor to Si and Ge, and can also be used in semiconductor materials like SIC or diamond. Second-generation GaAs semiconductor materials, InP compound semiconductor material materials, and third generation semiconductor materials. It is strong in anti-radiation, has high direct bandgaps, strong atomic bonds and good chemical stability. This material is widely used in optoelectronics as well as high power, high temperature devices.
What does a charge for gallium-nitride be?
The third-generation semiconductor core materials are known to be gallium nitride. The bandgap of gallium nitride, compared to silicon is wider. Because of its wider bandgap, gallium nitride has higher resistance to high voltages and better conductivity than silica. With the materials contained in the same volume as silicon, gallium-nitride performs much better than silica.
Galium nitride makes up a larger percentage of many power management devices. Gallium nitride is a good charger for faster charging.
The most obvious benefit for users is the faster charging. However, it will not cause an increase in volume. Due to the GaN characteristics, the charger can achieve small dimensions and lighter weights. It also generates heat more efficiently and has an increased capacity. It is common for many products to have a significantly lower heating efficiency, including charging heads and CPUs.
Pricing for gallium nitride charger
These chargers for gallium-nitride batteries are easy to use. These chargers are smaller than other types and have a much greater efficiency. Although they can be used to meet modern day needs, the price is quite high.
The current market price for the 120w GaN battery charger is around 300 yuan. That’s twice as much or more than the 120w GaN notebook charger. Also, it isn’t too small. While the 95w GaN charger costs about the same price, 120W GaN charges three times as much. A 120w GaN charging station costs the equivalent of an average 120w laptop charger and a 65w GaN charge.
