- 1. 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)
- 2. Phys. Rev. B 62, 16572 (2000) , “Magneto-optical studies of the 0.88-eV photoluminescence emission in electron-irradiated GaN”, Mt. Waganer, I. A. Buyanova, N. Q. Thinh, W. M. Chen, B. Monemar, J. L. Lindstr?m, H. Amano, I. AkasakiProperties of the 0.88-eV photoluminescence (PL) in electron-irradiated wurtzite GaN have been investigated in detail by a combination of various magneto-optical techniques, including Zeeman measurements of PL, optically detected magnetic resonance (ODMR), and level anticrossing (LAC). ODMR... (Read more)
- 3. 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)

(b) 221, 625-631 (2000) , “Identification of the Gold-Lithium Defect L1 in Silicon with the Trigonal Centre Au2--(Li+)3 by Electrical, Optical and Magnetic Resonance Spectroscopy”, B. Langhanki, J. ?M. SpaethN-type silicon doped with gold and lithium was investigated by Electron Paramagnetic Resonance (EPR) and Deep Level Transient Spectroscopy (DLTS), using two sets of samples with different defect concentrations of both gold and lithium. Photoluminescence (PL) on both sets of samples allowed to... (Read more)

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...
