- 1. Phys. Rev. B 74, 153201 (2006) , “Light-induced hyperfine 69Ga shifts in semi-insulating GaAs observed by optically polarized NMR”, Kannan Ramaswamy, Stacy Mui, and Sophia E. HayesWe report the observation of 69Ga NMR light induced hyperfine shifts at 6 K in semi-insulating GaAs detected by optically polarized nuclear magnetic resonance in a magnetic field of 4.7 T. The main features of the observed shift are a systematic change in the absolute shift value as the... (Read more)
- 2. Phys. Rev. B 69, 45207 (2004) , “Intrinsic defects in GaN. I. Ga sublattice defects observed by optical detection of electron paramagnetic resonance”, K. H. Chow, L. S. Vlasenko, P. Johannesen, C. Bozdog, G. D. Watkins, Akira Usui, Haruo Sunakawa, Chiaki Sasaoka, Masashi MizutaIrradiation of GaN by 2.5-MeV electrons in situ at 4.2 K produces a broad photoluminescence (PL) band centered at 0.95 eV. Optical detection of electron paramagnetic resonance (ODEPR) in the band reveals two very similar, but distinct, signals, L5 and L6, which we identify as interstitial... (Read more)
- 3. Appl. Phys. Lett. 80, 1334 (2002) , “Production of nitrogen acceptors in ZnO by thermal annealing”, N. Y. Garces, N. C. Giles, L. E. Halliburton, G. Cantwell, D. B. Eason, D. C. Reynolds, D. C. LookNitrogen acceptors are formed when undoped single crystals of zinc oxide (ZnO) grown by the chemical-vapor transport method are annealed in air or nitrogen atmosphere at temperatures between 600 and 900 °C. After an anneal, an induced near-edge absorption band causes the crystals to appear... (Read more)
- 4. Phys. Rev. Lett. 85, 2761 (2000) , “Detection of Interstitial Ga in GaN”, K. H. Chow, G. D. Watkins, Akira Usui, M. MizutaWe report the direct detection of interstitial Ga by optical detection of electron paramagnetic resonance (ODEPR) in the photoluminescence of n-type GaN after irradiation in situ at 4.2 K with 2.5 MeV electrons. It is stable upon annealing until room temperature, where it becomes mobile and trapped... (Read more)
- 5. Phys. Rev. B 59, 12479-12486 (1999) , “Optical detection of electron paramagnetic resonance in electron-irradiated GaN”, C. Bozdog, H. Przybylinska, G. D. Watkins, V. H?rle, F. Scholz, M. Mayer, M. Kamp, R. J. Molnar, A. E. Wickenden, D. D. Koleske, R. L. Henry2.5 MeV electron irradiation of wurtzite GaN epitaxially grown on sapphire substrates greatly reduces its near-UV and visible luminescence, producing two bands in the near infrared. In one of these, a broad structureless band centered at ∼0.95 eV, three optically detected S=1/2 electron...
