Application prospect of gallium nitride
What is gallium-nitride?
A wide-bandgap, composite semiconductor material is gallium nitride. According to a third party, standard mobile chargers for smartphones can either reduce their weight by as much as 40%, or produce more power in the same space. The charger can be used for consumer, industrial and automotive electronic products. These products are intended to be used as power supplies for consumer electronics, including chargers, external power adapters, led lighting drivers and televisions.
Gallium nitride application prospect
Heteroepitaxial defects are very common in GaN materials. This is because one substrate crystal hasn't been solved for quite some time. However, this has made it practical to make the devices. Niya Chemical created 1200mcd LEDs in 1994. In 1995 it produced Zcd blue LED (450nmLED), green light 12cd (12cd) (520nmLED). In 1998 Japan devised a seven year plan to develop wide band gap Nitride materials for LEDs. By 2005, high-energy ultraviolet LEDs will be developed that emit white light and are enclosed in fluorescent tubes. White LEDs consume only 1/8 the energy of traditional incandescent bulbs and half that of fluorescent lamps. Their life span is between 50 and 100 times longer than those used for fluorescent lamps. These results prove that GaN materials have been developed successfully and are now in the practice stage. InGaN systems alloys, InGaN/AlGaN two junction LED, InGaN single and multiple quantum-well LED, as well as InGaN multiple LEDs are all possible. They have been created successfully. Two high-brightness, high-purity InGaNSQWLED6cd green teas and two high-brightness LEDs of the same color have been developed. AlGaP series of red LEDs and AlGaAs-series blue LEDs can be combined to create a bright, full-color display. This combination of the white light source and three primary colors opens new applications. LEDs that are reliable and last a long time will soon be the norm. Light bulbs and fluorescent lamps will be replaced by LEDs. LED will soon be the top-selling product. GaN transistors are expected to rapidly develop with material growth, device technology, and will be a new generation high-temperature frequency/high-power devices.
Galium nitride's disadvantages and issues
In theory, this carrier's effective mass is high due to the energy band structure. However, its transport property and low low electric field mobility make it difficult for low-frequency performances and low electric fields. The other side is that single GaN GaN crystals grown using heteroepitaxy (using SiC and sapphire as substrates), aren't very good, which hinders the development GaN devices. For instance, dislocation density can exceed 1081010/cm2 (despite the similarity of the sapphire crystal structure and SiC as substrates), the background carrier (electron) concentration at room temperature of undoped GaN is as high 1017cm-3. It could possibly be related to substituteal Si, substitutional M, and other factors. And it shows ntype conductivity. It is possible to obtain ntype doping with Si (doping Si can achieve ntype GaN with electron concentrations of 10151020/cm3 with room temperature mobility>300cm2/V.s), but the ptype doping level is too low. Mostly doped with Mg, the hole concentration is only 10171018/cm3, mobility>10 cm2/V.s. and the doping efficiency is mainly due to high self-ionization energy and to Mg).
Galium nitride price
Price will depend on how large and pure the gallium nitride particles are. The purchase volume may also have an effect on the price. Large quantities of small amounts will result in a lower price. On our official website, you can see the price for gallium Nitride.
