What is gallium nitride? Gallium nitrideis a semiconductor material for broadband GAP composite materials. According to the calculation of a third party, after using the GAN device, the standard mobile phone charger can reduce the weight by up to 40 % or output more power under the same size conditions. It suits consumers, industry, cars, and other electronic products. The target application of this series includes the built-in power supply of consumer electronics, such as chargers, PC external power adapters, LED lighting drives, TV.
Advantages and advantages of gallium nitride ① Large bandgap width (3.4eV), high thermal conductivity (1.3W/cm-K), high operating temperature, high breakdown voltage, and strong radiation resistance ② The bottom of the conduction band is at Γ Point, and the energy difference between the point and other energy valleys in the conduction band is large, so it is not easy to generate intervalley scattering so that a high strong field drift velocity can be obtained (the electron drift velocity is not easy to saturate) ③ GaN is easy to form mixed crystals with AlN, InN, etc., and can be made into various heterostructures. 2-DEG with mobility of 105 cm2/Vs. at low temperature has been obtained (because of its high surface density, 2-DEG effectively shields optical phonon scattering, ionized impurity scattering, piezoelectric scattering, and other factors)
GaN photoelectric device After the successful development of group III nitride blue LED, the focus of research began to turn to the development of group III nitride blue LED devices. Blue LED has broad application prospects in the fields of optical measurement and high-density optical storage of information. At present, Nichia is the world leader in the field of GaN blue LED, and its GaN blue LED has a continuous working life of 2 mW at room temperature of more than 10000 hours. HP has successfully developed a ridge waveguide refractive index guided GaInN/AlGaN multi-quantum well blue LED with sapphire as the substrate. CreeResearch is the first company to report the CWRT blue laser made on SiC. The laser has a transverse device structure. Following companies such as Nichia, CreeResearch, and Sony, Fujitsu announced the development of InGaN blue laser, which can be used in CW at room temperature. Its structure is grown on SiC substrate and adopts a vertical conductive structure (P-type and n-type contacts are made on the top and back of the wafer, respectively). This is the first reported CW blue laser with a vertical device structure. In terms of the detector, GaN ultraviolet detector has been developed with a wavelength of 369 nm, and its response speed is comparable to that of the Si detector. However, this research is still in its infancy. GaN detectors will have important applications in flame detection, early missile warning, etc.
