- 1. Phys. Rev. B 75, 035322 (2007) , “Ab initio study of electronic and magnetic properties of the C-codoped Ga1−xMnxN (100) surface”, Q. Wang, Q. Sun, and P. JenaFirst principles calculations based on gradient corrected density functional theory have been carried out to study the magnetic coupling between Mn atoms in pure and carbon doped Ga1−xMnxN thin films. We show that the ground state of Mn-doped GaN (100) thin... (Read more)
- 2. Phys. Rev. B 68, 085202 (2003) , “Physics and chemistry of hydrogen in the vacancies of semiconductors”, Bernadett Szûcs, Adam Gali, Zoltán Hajnal, Peter Deák, and Chris G. Van de WalleHydrogen is well known to cause electrical passivation of lattice vacancies in semiconductors. This effect follows from the chemical passivation of the dangling bonds. Recently it was found that H in the carbon vacancy of SiC forms a three-center bond with two silicon neighbors in the vacancy, and... (Read more)
- 3. 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)
- 4. Physica B 308-310, 51-57 (2001) , “Magnetic resonance studies of defects in GaN with reduced dislocation densities”, E. R. Glaser, J. A. Freitas, Jr. , G. C. Braga, W. E. Carlos, M. E. Twigg, A. E. Wickenden, D. D. Koleske, R. L. Henry, M. Leszczynski, I. Grzegory, T. Suski, S. Porowski, S. S. Park, K. Y. Lee and R. J. MolnarMagnetic resonance experiments, including optically detected magnetic resonance (ODMR) and electron paramagnetic resonance (EPR), have been performed on Si-doped homoepitaxial GaN layers grown by MOCVD and on high quality, free-standing (200 μm-thick) GaN grown by HVPE. This allowed us to... (Read more)
