What is annealing for III-Nitrides?5 answersAnnealing for III-Nitrides refers to the process of using high temperature and high pressure conditions to recover the crystalline quality and activate dopants in III-Nitride materials such as GaN. Ion implantation is a common method used to introduce dopants into the host matrix, but it also causes lattice damage. Post-implant annealing at high temperatures is necessary to recover the crystalline quality and activate the dopants. However, extreme annealing conditions can lead to the formation of conducting paths along dislocations, which deteriorate the electrical properties of the p-n junction. The annealing process can be improved by using weighted cover systems to prevent the escape of nitrogen during annealing. Special measures, such as AlN-capping and applying ultra-high nitrogen pressures, are required to protect the surface from nitrogen loss during high temperature annealing. The optimum annealing temperature for III-Nitrides like GaN is closer to 1700°C to fully remove the implant damage and achieve good dopant activation.
