- 1. Phys. Rev. B 77, 085120 (2008) , “Identification of the carbon antisite in SiC: EPR of 13C enriched crystals”, Pavel G. Baranov, Ivan V. Ilyin, Alexandra A. Soltamova, and Eugene N. MokhovAn electron paramagnetic resonance spectrum with axial symmetry along c axis, spin S=1/2 and strong hyperfine interaction with one carbon atom has been observed in neutron-irradiated and annealed 6H-SiC, 13C isotope enriched. The 13C concentration was... (Read more)
- 2. Phys. Rev. Lett. 98, 216103 (2007) , “Influence of Cumulenic Chains on the Vibrational and Electronic Properties of sp-sp2 Amorphous Carbon”, L. Ravagnan, P. Piseri, M. Bruzzi, S. Miglio, G. Bongiorno, A. Baserga, C. S. Casari, A. Li Bassi, C. Lenardi, Y. Yamaguchi, T. Wakabayashi, C. E. Bottani, and P. MilaniWe report the production and characterization of a form of amorphous carbon with sp-sp2 hybridization (atomic fraction of sp hybridized species 20%) where the predominant sp bonding appears to be (=C=C=)n cumulene....

- 3. Phys. Rev. B 74, 235426 (2006) , “First-principles study of electronic properties of hydrogenated graphite”, A. Allouche and Y. FerroProgressive implantation of hydrogen atoms into graphite is modeled by first-principles density functional theory. The maximum H/C ratio was found at 53%, which is in good agreement with experimental results. The hydrogen trapping energy varies from −0.7 eV at very low concentrations to a... (Read more)
- 4. Phys. Rev. B 73, 033204 (2006) , “Electrical characterization of metastable carbon clusters in SiC: A theoretical study”, A. Gali, N. T. Son, E. JanznFirst-principles calculations carried out in 3C- and 4H-SiC show that small metastable carbon clusters can be created in irradiated SiC. The metastable carbon clusters possess occupation levels in the p-type as well as in the n-type 4H-SiC. Depending on the... (Read more)
