- 1. Appl. Phys. Lett. 90, 051902 (2007) , “Recombination processes in undoped and rare-earth doped MAl2O4 (M=Ca,Sr) persistent phosphors investigated by optically detected magnetic resonance”, Stefan Schweizer, Bastian Henke, Uldis Rogulis, and William M. YenThe authors present magneto-optical measurements on single-crystal MAl2O4 (M=Ca and Sr) persistent phosphors that are nominally pure or doped with Eu and Nd or Dy, respectively. Their recombination luminescence (RL) and microwave-induced changes in the RL in a... (Read more)
- 2. Phys. Rev. B 69, 45208 (2004) , “Intrinsic defects in GaN. II. Electronically enhanced migration of interstitial Ga observed by optical detection of electron paramagnetic resonance”, P. Johannesen, A. Zakrzewski, L. S. Vlasenko, G. D. Watkins, Akira Usui, Haruo Sunakawa, Masashi MizutaOptical excitation at 1.7 K with 364-nm laser light produces partial annealing recovery of the damage produced in GaN by 2.5-MeV electron irradiation in situ at 4.2 K. Observed is a reduction in the irradiation-produced 0.95-eV photoluminescence (PL) band, recovery in the visible... (Read more)
- 3. 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)
- 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)
