ABSTRACTP-type GaN films were grown on sapphire substrates in a horizontal metalorganic chemical vapor deposition system using (C5H5)2Mg (Cp2Mg) as the p-dopant source. It is found that the acceptor concentration in the post-growth annealed GaN samples increases with the Mg flow rate and reaches a peak value of 1×1019 cm−3 at Mg flow rate of 0.84 ĉmol/min. The films remain semi-insulating even after annealing when the Mg flow rate is higher than 1.08 ĉmol/min. The effects of annealing temperature and duration on the electrical properties of GaN are also investigated. The results confirm that a 800 °C, 30 minutes post-growth annealing in N2 ambient is sufficient to activate most of the Mg atoms. In addition, study of rapid thermal annealing of Mg-doped GaN was carried out and the results show that the p-type acceptor concentration obtained is comparable to the results obtained using furnace annealing process. Finally, GaN light emitting diodes (LEDs) are demonstrated using undoped layer as the n-type base layer in a p-on-n structure. The light emission spectra are dominated by the 430 nm peak, accompanied with two relatively weak peaks located at 380nm and 550nm.
