- 1. phys. stat. sol. (b) 245, 1298-1314 (2008) , “EPR identification of intrinsic defects in SiC”, J. Isoya, T. Umeda, N. Mizuochi, N. T. Son, E. Janzen, T. OhshimaThe structure determination of intrinsic defects in 4H-SiC, 6H-SiC, and 3C-SiC by means of EPR is based on measuring the angular dependence of the 29Si/13C hyperfine (HF) satellite lines, from which spin densities, sp-hybrid ratio, and p-orbital direction can be determined over...

- 2. Phys. Rev. B 61, 12939 (2000) , “Dimer of Substitutional Carbon in Silicon Studied by EPR and ab initio Methods”, J. R. Byberg, B. Bech Nielsen, M. Fanciulli, S. K. Estreicher, P. A. Fedders.An EPR signal observed in carbon-doped float-zone silicon after irradiation with 2-MeV electrons at room temperature has been investigated. It represents a defect with S=1/2, an apparently isotropic g factor (=2.0030), and a complicated hyperfine structure from 29Si nuclei in five shells... (Read more)
- 3. Phys. Rev. B 58, 9845 (1998) , “Theory of Carbon-Carbon Pairs in Silicon”, R. B. Capaz, A. Dal Pino, Jr., J. D. Joannopoulos.Interstitial-substitutional carbon pairs (CiCs) in silicon display interesting metastable behavior associated with two different structural configurations. In this work, we perform extensive ab initio calculations on this system. Our results show the following. (i) The... (Read more)

Torres.Interstitial carbon, Ci, defects in Si exhibit a number of unexplained features. The Ci defect in the neutral charge state gives rise to two almost degenerate vibrational modes at 920 and 931 cm-1 whose 2:1 absorption intensity ratio naturally suggests a trigonal... (Read more)
- 5. Phys. Rev. B 47, 6363-6380 (1993) , “Electron paramagnetic resonance of multistable interstitial-carbonsubstitutional-group-V-atom pairs in silicon”, X. D. Zhan, G. D. WatkinsA total of five new electron paramagnetic resonance (EPR) centers are observed in electron-irradiated P-, As-, and Sb-doped silicon. Three are identified as arising from the neutral charge state of the stable configuration and two of the four metastable configurations of an... (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)
- 8. Phys. Rev. Lett. 36, 1329 (1976) , “EPR Observation of the Isolated Interstitial Carbon Atom in Silicon ”, G. D. Watkins and K. L. BrowerAn EPR spectrum, labeled Si-G12, is identified as arising from an isolated interstitial carbon atom in silicon. A ?100? C-Si interstitialcy model is suggested for the defect in which a silicon and carbon atom pair partially share single substitutional site. Because carbon is isoelectronic with... (Read more)

Brower.An electron-paramagnetic-resonance (EPR) study of irradiated, p-type silicon doped with carbon enriched with 13C has revealed that the Si-G 11 spectrum possesses a 13C hyperfine structure. Owing to the complexity and lack of resolution in the observed spectrum, we found it... (Read more)
