- 1. Phys. Rev. B 71, 115204 (2005) , “Electron Spin Resonance Study of Paramagnetic Centers in Neutron-Irradiated Heat-Treated Silicon”, D. Pierreux and A. StesmansElectron spin resonance (ESR) was used to study neutron-induced defects in silicon as functions of anneal temperature Tan. For Tan below 200 °C, the ESR response is dominated by the Si-P3 and Si-P6 spectra, as observed before. At Tan=200 ... (Read more)
- 2. Phys. Rev. B 64, 245212 (2001) , “Structure of the silicon vacancy in 6H-SiC after annealing identified as the carbon vacancy-carbon antisite pair”, Th. Lingner, S. Greulich-Weber, J.-M. Spaeth, U. Gerstmann, E. Rauls, Z. Hajnal, Th. Frauenheim, H. OverhofWe investigated radiation-induced defects in neutron-irradiated and subsequently annealed 6H-silicon carbide (SiC) with electron paramagnetic resonance (EPR), the magnetic circular dichroism of the absorption (MCDA), and MCDA-detected EPR (MCDA-EPR). In samples annealed beyond the annealing... (Read more)
- 3. Phys. Rev. B 56, 7384 (1997) , “Negatively charged Si vacancy in 4H SiC: A comparison between theory and experiment”, T. Wimbauer, B. K. Meyer, A. Hofstaetter, A. Scharmann, H. OverhofWe use electron paramagnetic resonance and electron nuclear double resonance to identify the negatively charged Si vacancy in neutron-irradiated 4H SiC. The identification is based on resolved ligand hyperfine interactions with carbon and silicon nearest and next nearest neighbors and on the... (Read more)
- 4. Phys. Rev. Lett. 48, 37 (1982) , “Optical Detection of Magnetic Resonance for a Deep-Level Defect in Silicon”, K. M. Lee, K. P. O'Donnell, J. Weber, B. C. Cavenett, and G. D. WatkinsOptical detection of magnetic resonance is reported for the 0.97-eV luminescence in neutron-irradiated silicon. The resonance is of an excited triplet (S=1) state of the defect, which is not the radiative state, known to be a singlet (S=0). The spectrum is unusual in that it is characteristic of a...

- 5. Phys. Rev. B 14, 4506 (1976) , “EPR study of neutron-irradiated silicon: A positive charge state of the <100> split di-interstitial”, Young-Hoon Lee, Nikolai N. Gerasimenko, and James W. CorbettThe Si-P6 spectrum shows an intrinsic tetragonal symmetry with the C2 axis along ?100? and distortion forces the principal axes of the g tensor to be displaced in the {100} plane. The g tensor previously identified by Jung and Newell was found to be due to the motionally averaged state... (Read more)
- 6. Phys. Rev. B 9, 4351-4361 (1974) , “EPR study of defects in neutron-irradiated silicon: Quenched-in alignment under <110>-uniaxial stress”, Young-Hoon Lee and James W. CorbettThe stress effect in an EPR study is first treated rigorously in terms of the piezospectroscopic tensor, taking account of the local symmetry of a defect. It is found that the degree of alignment (n?/n?) provides incisive information on the structure of a defect; in general, a... (Read more)
- 7. Phys. Rev. B 8, 2810 (1973) , “EPR Studies in Neutron-Irradiated Silicon: A Negative Charge State of a Nonplanar Five-Vacancy Cluster (V5-)”, Y. H. Lee, J. W. Corbett.EPR studies are carried out for the float-zone intrinsic silicon irradiated with reactor neutrons up to the total fluence 1018 n/cm2. Details of the Si29 hyperfine structure and of the g tensor in the P-1 spectrum are observed with respect to temperature from 77 to...
