In recent years, with the maturity of technology, nitride materials have been applied in many other fields, such as energy storage, optoelectronics, display, LED, solar energy, etc. 1. energy storage The application of nitride materials in energy storage devices has attracted more and more attention in recent years. As a new generation of energy storage devices, lithium ion batteries (LIBs) have the advantages of high energy density, long life, no memory effect and environmental friendliness. However, the safety of LIBs has always been a concern. In particular, the flammability of the electrolyte is the main cause of battery fires and explosions. In order to solve the safety problem of LIBs, solid state batteries (SSBs) have been proposed. Compared with traditional LIBs, SSBs have the advantages of high safety, long life and high energy density. The key to the development of SSBs lies in the material of the solid electrolyte. Among various solid electrolytes, nitride materials have attracted more and more attention because of their excellent ionic conductivity and thermal stability. The main application of nitride materials in energy storage is lithium ion batteries (LIBs). The working principle of LIBs is that when the battery is charging, the lithium ions in the electrolyte are adsorbed on the anode (generally made of carbon), and when the battery is discharging, the lithium ions in the electrolyte are desorbed from the anode and transferred to the cathode. The anode and cathode are separated by a solid electrolyte. In recent years, nitride materials have been widely used in LIBs due to their excellent ionic conductivity and thermal stability. In particular, the application of solid state electrolytes based on nitride materials has greatly improved the safety and high temperature performance of LIBs. 2. optoelectronics Optoelectronic devices are devices that convert light into electricity or electricity into light. They are widely used in our daily life, such as mobile phones, computers, TVs, etc. In recent years, with the rapid development of optoelectronic devices, the demand for nitride materials has increased rapidly. The main application of nitride materials in optoelectronic devices is light emitting diodes (LEDs). The working principle of LEDs is that when a forward current flows through the junction of n-type and p-type semiconductors, electrons and holes recombine to generate photons, and the photons are emitted in the form of light. The most important material of LEDs is nitride semiconductor materials. In particular, gallium nitride (GaN) and indium gallium nitride (InGaN) are the most widely used materials. They have the advantages of high electron mobility, high light output power and low operating voltage. 3. display Display devices are devices that display information in the form of images. They are widely used in our daily life, such as mobile phones, computers, TVs, etc. In recent years, with the rapid development of display technology, the demand for nitride materials has increased rapidly. The main application of nitride materials in display devices is liquid crystal display (LCD). LCD is a kind of display device that uses liquid crystal to control the light transmission. The working principle of LCD is that when the electric field is applied, the liquid crystal molecules will align in the direction of the electric field, and when the electric field is removed, the liquid crystal molecules will return to the original state. The most important material of LCD is indium tin oxide (ITO). ITO is a kind of transparent conducting oxide, which has the advantages of high transparency, low resistivity and high stability. 4. solar energy Solar energy is a kind of renewable energy. It is widely used in our daily life, such as solar water heaters, solar street lights, solar photovoltaic power generation, etc. In recent years, with the rapid development of solar energy technology, the demand for nitride materials has increased rapidly. The main application of nitride materials in solar energy is solar cells. Solar cell is a kind of device that converts solar energy into electrical energy. The working principle of solar cell is that when the sunlight hits the solar cell, the photons in the sunlight will be absorbed by the solar cell, and the electrons in the solar cell will be excited to the conduction band. The most important material of solar cell is silicon. Silicon has the advantages of high photoelectric conversion efficiency, low cost and good stability. 5. LED LED is a kind of semiconductor device that can convert electrical energy into light energy. The working principle of LED is that when a forward current flows through the junction of n-type and p-type semiconductors, electrons and holes recombine to generate photons, and the photons are emitted in the form of light. LED has the advantages of high efficiency, low power consumption, long life, environmental friendliness, etc. In recent years, LED has been widely used in lighting, signage, backlight, display, decoration, etc. The most important material of LED is nitride semiconductor materials. In particular, gallium nitride (GaN) and indium gallium nitride (InGaN) are the most widely used materials. They have the advantages of high electron mobility, high light output power and low operating voltage.
