ScholarBank@NUS Repository. https://doi.org/10.1002/pssc.200461458 | Abstract: | P-type doping through Be implantation in GaN is achieved by a two-step annealing process. Combined photoluminescence-Raman measurements showed Be-related band, indicating a low acceptor ionization energy of 140 meV, and resonance Raman features. X-ray diffraction revealed the lattice expansion due to Be-implantation. Scanning electron microscopy exhibited the surface defects morphology with hexagonal plane like inverse open pyramids. The effect of new annealing process on Be activation is discussed. © 2005 WILEY-VCH Verlag GmbH & Co.
