What is gallium-nitride? Gallium nitride (chemical formula GaN) is a combination of nitrogen and galium. This compound makes a semiconductor with an energy gap. This compound has been used since 1990 in LEDs. It is similar in structure to wurtzite, and exhibits high hardness. GaN is capable of operating in optoelectronic devices with high power and speed due to its large energy gap (3.4 electron volts). GaN is a good choice for purple laser diodes, which can generate violet lasers by using standard semiconductor-pumped solid state lasers.

Benefits and disadvantages of gallium-nitride
Lattice symmetry in GaN is low. It is either a hexagonal wurtzite or a tetragonal metastable, sphalerite, structure. Also, it has strong piezoelectricity and ferroelectricity. Strong piezoelectric Polarization: This is where 2-DEG's surface density is increased to 1013/cm2 in AlGaN/GaAs heterostructure. This makes 2-DEG very useful for device working. GaN's advantages outweigh the disadvantages. Its effective transport performance, especially through its role in heterojunction is no less than that of GaAs. The effect of making microwave output power devices (microwave output power density), is frequently far better than any other semiconductor material.

Problems with gallium nitride
GaN has a broad band gap semiconductor, but its polarity makes it difficult for high-doping to make better metal-semiconductor contacts. This problem is very difficult in GaN manufacturing. This is why the GaN devices' performance often depends on the manufacturing results for ohmic contact. A better option is heterojunction. To achieve an ohmic touch, first let the band gap transition slowly to smaller. Then, use high doping. However, this is not an easy process. Ohmic contact in GaN device production is, therefore, a significant problem.

Properties and stability galium nitride
When stored properly, the product will not become brittle. Avoid contact with oxygen, heat, or moisture/humidity. GaN is beginning to disintegrate at 1050: GaN (s),=2Ga(g)+N2 [g]. According to X-ray Diffraction, GaN crystal is a hexagonal crystal of the fibrous zincate type. GaN becomes unstable at higher temperatures than helium or nitrogen. The vapor pressure of GaN at 1130 degrees Celsius is below the value calculated by enthalpy or entropy. This is due to the existence of polymer molecular (GaNx) which is not cold, hot, concentrated hydrochloric, nitric or sulfuric acids or the cold 40% HF. You can also dissolve it in hot alkali, but not in cold concentrated alkali.

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.
