Multicycle rapid thermal annealing technique and its application for the electrical activation of Mg implanted in GaN

摘要

No reliable results were reported up-to-date on electrical activation of Mg implanted GaN without co-doping with other ions. The main reason of the poor ion-implanted activation in GaN is lack of the adequate GaN annealing technique. We have developed a new approach, Multicycle Rapid Thermal Annealing to overcome this limitation and enable longer annealing times at high temperature. We have applied this new technique to Mg-implanted GaN, and demonstrated p-type conductivity.
