摘要

In this study, Mg-doped GaN epitaxial layers were grown by metalorganic vapor phase epitaxy (MOVPE) and annealed in O₂, air and N₂. It was found that we could achieve a low-resistive p-type GaN by O₂-ambient annealing at a temperature as low as 400°C. The resistivity and hole concentration of the 400°C O₂-ambient annealed Mg-doped GaN was 2 Ω-cm and 3 × 10¹⁷ cm^-3, respectively. These values are equivalent to those values obtained from Mg-doped GaN annealed in N₂ ambient at 700°C.
