Overview of Gallium Nitride

wallpapers Technology 2021-08-11
Gallium Nitride (GaN) is a semiconductor with a large bandgap, which belongs to the list of wide bandgap semiconductors.
Gallium nitride is an excellent material for microwave power transistors. It is a new type of semiconductor material for the development of microelectronic devices and optoelectronic devices. It has a wide direct bandgap, strong atomic bonds, high thermal conductivity, and good chemical stability (almost no acid corrosion) and other properties and strong resistance to radiation.
Properties of Gallium Nitride
It will not decompose if used and stored in accordance with specifications.
Avoid contact with oxides, heat, moisture.
GaN starts to decompose at 1050°C: 2GaN(s)=2Ga(g)+N2(g). X-ray diffraction has pointed out that GaN crystal belongs to the hexagonal system of the wurtzite lattice type.
In nitrogen or helium, when the temperature is 1000°C, GaN will slowly volatilize, which proves that GaN is stable at higher temperatures. At 1130°C, its vapor pressure is lower than the value calculated from enthalpy and entropy. It is due to the presence of polymer molecules (GaN) x.
Gallium Nitride is not decomposed by cold or hot water, dilute or concentrated hydrochloric acid, nitric acid and sulfuric acid, or cold 40% HF. It is stable in cold concentrated alkali, but it can be dissolved in alkali when heated.
The preparation method of Gallium Nitride
1. Nitrogen and gallium do not react directly even at 1000°C. The loose gray powdery gallium nitride GaN can be obtained by heating metal gallium at 1050-1100°C for 30 minutes in an ammonia gas stream. The addition of ammonium carbonate can provide gas to agitate the liquid metal and promote contact with the nitriding agent.
2. GaN can also be obtained by firing finely ground GaP or GaAs in a dry ammonia gas stream.
