Webbon impurity concentration is adjusted mainly by NH 3 flow rate during MOCVD—more NH 3 corresponds to less carbon impurity [17]. The rapid thermal annealing is carried out in a nitrogen environment at a temperature of 800°C for 3min to de-passivate the Mg– H complexes. Hall test is carried out to measure the resistivity of p-GaN samples.
