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 luminescence and high reflectivity 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.
Gallium Nitride is the most common material used for substrates of LED chips in semiconductor lighting. 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 stability and chemical resistance. 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. As a semiconductor high-temperature material, gallium-nitride materials are mainly used to make electronic devices like transistors and field effect transistors for flight control systems and fire control. In the area of power transmission and delivery, high-temperature devices like power electronic converters and switches can be made using gallium nitride. This improves the efficiency and reliability of the 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 (around 2.3eV), allowing them to absorb more sunlight, and thus have 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. Gallium nitride is also used for environmental monitoring to produce detectors like gas and photochemical sensor, which detect environmental parameters, such air quality, pollutants, and other environmental parameters.
5. 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 electronic mobility transistors and microwave monolithic combined circuits. These are used in fields like radar, communications, and electronic countermeasures. Moreover, gallium nitride It can also be used for the manufacture of high-power lasers and deep ultraviolet optoelectronic gadgets.
