- 1. Phys. Rev. B 65, 85312 (2002) , “Magnetic resonance studies of Mg-doped GaN epitaxial layers grown by organometallic chemical vapor deposition”, E. R. Glaser, W. E. Carlos, G. C. B. Braga, J. A. Freitas Jr, W. J. Moore, B. V. Shanabrook, R.L. Henry, A. E. Wickenden, D. D. Koleske, H.Obloh, P. Kozodoy, S. P. DenBaars, U. K. MishraElectron paramagnetic resonance (EPR) and optically detected magnetic resonance (ODMR) experiments have been performed on a set of GaN epitaxial layers doped with Mg from 2.5×1018 to 5.0×1019 cm-3. The samples were also characterized by secondary-ion-mass... (Read more)

Shahedipour, B. W. WesselsIrradiation of p-type (Mg-doped) GaN in situ at 4.2 K by 2.5 MeV electrons reduces the visible luminescence and creates a broad luminescence band in the infrared at ?0.95?eV. Upon annealing at 180 K, partial recovery of the visible luminescence occurs and a well resolved S=1 center is observed by... (Read more)
- 3. 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. Lindström, 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...

- 4. phys. stat. sol. (a) 162, 95-151 (1997) , “EPR and ENDOR Investigations of Shallow Impurities in SiC Polytypes”, S. Greulich-WeberInvestigations of nitrogen donors in 6H-, 4H- and 3C-SiC using conventional electron paramagnetic resonance (EPR), electron nuclear double resonance (ENDOR) and optical detection of EPR and ENDOR as well as optical absorption and emission spectroscopy are reviewed and critically discussed. An... (Read more)
- 5. Phys. Rev. B 43, 6569 (1991) , “Optically detected magnetic resonance of dislocations in silicon”, V. Kveder, P. Omling, H. G. Grimmeiss, Yu. A. OsipyanThe observation of optically detected magnetic resonance (ODMR) signals directly correlated with dislocations in silicon is reported. The ODMR signals are identified as resonances from free electrons, dangling bonds, and quasifree holes bound to a one-dimensional potential in straight dislocations.... (Read more)
- 6. Phys. Rev. B 42, 5765 (1990) , “Bistable interstitial-carbonsubstitutional-carbon pair in silicon”, L. W. Song, X. D. Zhan, B. W. Benson, and G. D. WatkinsA bistable interstitial-carbon–substitutional-carbon pair has been identified in electron-irradiated silicon by a combination of several spectroscopic experimental techniques. In the positive and negative charge states, the stable configuration of the defect involves a carbon-silicon ‘‘molecule’’... (Read more)
- 7. Phys. Rev. Lett. 60, 460 (1988) , “Bistable Defect in Silicon: The Interstitial-Carbon-Substitutional-Carbon Pair”, L. W. Song, X. D. Zhan, B. W. Benson, G. D. Watkins.By combining several spectroscopic techniques, we have observed a new type of bistable center in electron-irradiated silicon and have identified it as an interstitial-carbon–substitutional-carbon pair. The positive and negative charge states of the defect share a common stable configuration which... (Read more)
