- 1. J. Appl. Phys. 99, 114509 (2006) , “Influence of residual oxygen impurity in quaternary InAlGaN multiple-quantum-well active layers on emission efficiency of ultraviolet light-emitting diodes on GaN substrates”, Takashi Kyono, Hideki Hirayama, Katsushi Akita, Takao Nakamura, Masahiro Adachi, and Koshi AndoThe influence of residual impurities in quaternary InAlGaN active layers on the emission efficiency of 350 nm band ultraviolet light-emitting diodes on GaN substrates has been investigated. Secondary ion mass spectrometry and capacitance-voltage measurements have revealed that a large amount of... (Read more)
- 2. Appl. Phys. Lett. 87, 221903 (2005) , “Oxygen segregation to dislocations in GaN”, M. E. Hawkridge and D. ChernsThe structure and composition of threading dislocations in GaN grown by hydride vapor phase epitaxy have been examined by electron microscopy. Transmission electron microscopy showed that the core structure of screw dislocations varied widely, alternating irregularly between open core... (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)
