Basic characteristics of GaN and its ternary compounds
What is gallium nitride?
Gallium nitride (GaN) is a third-generation semiconductor material with a hexagonal wurtzite structure. GaN is one of the most interesting semiconductor materials in the world due to its wide band gap, high thermal conductivity, high-temperature resistance, radiation resistance, acid and alkali resistance, and high strength and hardness.
Basic characteristics of GaN and its ternary compounds
GaN-based materials mainly include GaN and its alloys with InN and AlN, and their band gap covers the entire visible and ultraviolet spectrum range. GaN and its ternary compounds usually exist in wurtzite structures with hexagonal symmetry but can also exist in sphalerite structures with cubic symmetry under certain conditions. The main difference between the two structures is that the stacking order of the atomic layer is different, so the electrical properties are also significantly different. Due to the unstable gan of sphalerite structure, wurtzite structure is generally used for devices. Table 1 shows the band gap width and lattice constants of GaN, inn and all of the two structures. The parameters of ingan, al gan, and other ternary compounds can be estimated by interpolation: GaN is the basic material in GaN-based semiconductor materials and the most studied group III nitride materials. Gan material is very hard, its chemical properties are very stable, it is insoluble in water, acid and alkali at room temperature, and its melting point is high, about 1700 ℃. The electrical properties of GaN are the main factors that determine the device's performance.
The electron mobility at room temperature can reach 900 cm2/. The background n-type carrier concentration of better GaN materials can be reduced to 1016/cm3. Due to the high concentration of n-type background carriers, the technical difficulties of preparing p-type samples once restricted the development of GaN devices. Akasaki et al. and Nakamura et al. achieved p-type of mg-doped gan samples by low-energy electron beam irradiation (see) and thermal annealing, respectively. P-type gan materials can be prepared with carrier concentrations between 1011 and 1020/cm3.
Application of GaN-based materials
Gan-based materials have the characteristics of a large band gap, high thermal conductivity, high electron saturation drift speed and low dielectric constant. Gan-based materials can manufacture blue, green, purple and white light diodes, blue and purple lasers, high-frequency and high-power electronic devices and ultraviolet light detectors. The manufacturing technology of diodes has been relatively mature and has been initially commercialized. The development of lasers is also very rapid and is moving towards commercialization. Other devices such as gan-based fet, heat, hot and uv optical sensors have also been developed.
