- 1. Phys. Rev. B 77, 195204 (2008) , “Identification of antisite carbon split-interstitial defects in 4H-SiC”, J. W. Steeds, W. SullivanA rich variety of optical centers with high energy local vibrational modes has been found in electron-irradiated 4H-SiC in both the as-irradiated and annealed states. These energies have been measured and the annealing dependence of the optical centers has been investigated by low-temperature... (Read more)
- 2. Phys. Rev. B 77, 195203 (2008) , “Creation and identification of the two spin states of dicarbon antisite defects in 4H-SiC”, J. W. Steeds, W. Sullivan, S. A. Furkert, G. A. Evans, P. J. WellmannThis paper deals with the positive identification by low-temperature photoluminescence microspectroscopy of the two spin states of the dicarbon antisites in 4H-SiC. The defects are created by high-dose electron irradiation at room temperature or by subsequent exposure to intense 325 nm radiation at... (Read more)
- 3. Phys. Rev. B 74, 140502(R) (2006) , “Lattice parameters and thermal expansion of superconducting boron-doped diamonds”, V. V. Brazhkin, E. A. Ekimov, A. G. Lyapin, S. V. Popova, A. V. Rakhmanina, S. M. Stishov, V. M. Lebedev, Y. Katayama, and K. KatoUsing two different high-pressure techniques, we have prepared boron-doped diamonds with atomic concentration of the dopant ranging from 0.04% to 4% (from 7×1019 to 7×1021 atom/cm3) and studied the lattice constants and thermal expansion of the diamonds...

Steeds, S. Furkert, J. M. Hayes, W. Sullivan, N. G. WrightRecent ab initio calculations [Mattausch et al., Phys. Rev. B 70, 235211 (2004)] of carbon clusters in SiC reveal a possible connection between the tricarbon antisite (C3)Si and the U photoluminescence center in 6H-SiC [Evans et al., Phys. Rev. B 66, 35204...
