The wide-gap semiconductor material GaN is widely used due to its excellent electrical, optical and physical properties.
1.Semiconductor light
Gallium Nitride is widely used in semiconductor lighting. The high transparency, reflectivity, luminescence and high brightness of gallium nitride material make it ideal for high-performance, LED lamps. LED lamps offer a higher level of luminous efficiency than fluorescent and incandescent bulbs, as well as a longer life span. This makes them suited for use in many fields, including indoor and exterior lighting, displays, automobile lighting, etc.
In semiconductor lighting materials such as gallium nitride are used mainly as substrates for the LED chips. LED chips, the main components of LED lighting, are directly responsible for the overall performance. They determine the LED light’s luminous efficacy and service life. Gallium Nitride is an excellent substrate material because it has high thermal conductivity. It also has high chemical stability and stability. It improves the LED chip’s luminous stability and efficiency, as well as reducing manufacturing costs.
2.High-temperature electronic devices
Gallium Nitride is also widely used for high-temperature electronics devices. Gallium nitride, which has high electron saturation rates and high breakdown electric fields, can be used for electronic devices that work in high-temperature environments.
Aerospace is a harsh field and it’s important to have electronic devices that work reliably in high temperature environments. Gallium nitride as a semiconductor high-temperature material is mainly used to make electronic devices like transistors and field effect transistors for flight control and control of fire systems. Gallium nitride is also used to produce high-temperature devices in the power transmission and distribution field, such as power electronics switches and converters. This improves the efficiency and reliability of equipment.
3.Solar cells
Gallium nitride solar cells also receive a lot attention. High-efficiency solar panels can be produced due to its high transparence and electron saturation rate.
Silicon is the main material in most traditional solar cells. Silicon solar cells are inexpensive to manufacture, but have a narrow bandgap (about 1eV), which limits their efficiency. Gallium-nitride solar cell have a greater energy gap width (about 2.30eV), which is able to absorb more sunlight, and has a higher photoelectric efficiency. The manufacturing cost of gallium-nitride cells is low. They can offer the same photoelectric converter efficiency for a lower price.
4.Detectors
Gallium Nitride is also widely used as a detector. They can be used to manufacture high-efficiency detectors like spectral and chemicals sensors.
Gallium Nitride can also be used as a material to make X-ray detectors that are efficient and can be applied in airports or important buildings for security checks. In environmental monitoring, materials such as gallium nitride are also used to manufacture detectors. These include gas and photochemical sensor devices that detect environmental parameters, such air quality, pollutants, and other environmental factors.
Other applications areas
Gallium nitride can be used for many different applications. Gallium nitride is used, for instance, to make microwave and high frequency devices such as high electron mobilty transistors (HEMTs) or microwave monolithic combined circuits (MMICs), that are used in fields like radar, communications, and electronic countermeasures. As well, gallium nitride It can also be used for the manufacture of high-power lasers and deep ultraviolet optoelectronic instruments.
