- 1. Mater. Sci. Eng. B 73, 60-63 (2000) , “EPR study of He-implanted Si”, B. Pivac, B. Rakvin, R. Tonini, F. Corni and G. OttavianiElectron paramagnetic resonance has been used to study the influence of thermal treatments on defect evolution in helium-implanted Czochralski single-crystal silicon. It is shown that the thermal treatment induces helium migration and capturing by vacancy clusters that transform into pressurized... (Read more)
- 2. Nucl. Instrum. Methods Phys. Res. B 170, 125-133 (2000) , “Electron Paramagnetic Resonance Study of S2 Defects in Hydrogen-Implanted Silicon”, B. Rakvin, B. Pivac, R. Tonini, F. Corni and G. OttavianiElectron paramagnetic resonance spectra of S2 paramagnetic center in Float zone silicon (FZ-Si) and Czochralski silicon (CZ-Si) produced by H+2 ion-implantation and by subsequent annealing have been studied. At room temperature the spectrum exhibits an isotropic line g=2.0066±0.0002, which,... (Read more)
- 3. Phys. Rev. B 61, 4659-4666 (2000) , “Identification of the Oxygen-Vacancy Defect Containing a Single Hydrogen Atom in Crystalline Silicon”, P. Johannesen, B. Bech Nielsen, J. R. Byberg.Float-zone and Czochralski-grown silicon crystals have been implanted with protons or deuterons at ?50 K. Electron paramagnetic resonance measurements reveal a new signal in the spectrum of the Czochralski-grown (oxygen-rich) material. This signal is strongly temperature dependent, displaying a...

KawazoeFour sets of ESR doublets with splittings of 9, 23, 26 or 44 mT were observed in dry a-SiO2 (Type IV, OH concentrations1017 cm−3) implanted with 29Si+ to a fluence of 6×1016 cm−2 at 160 keV. These doublets were attributed to the hyperfine structures due to a 29Si nucleus of... (Read more)
- 5. J. Non-Cryst. Solids 179, 39-50 (1994) , “Paramagnetic resonance of E′-type centers in Si-implanted amorphous SiO2. Si29 hyperfine structure and characteristics of Zeeman resonances*1”, H. Hosono, H. Kawazoe, K. Oyoshi, S. TanakaElectron paramagnetic resonance spectra were measured on SiO2 glasses implanted with Si ions to a fluence of 6 × 1016 cm−2 at an acceleration voltage of 160 kV. Three sets of doublets with different separation were observed in Si29-implanted substrates and were ascribed to primary... (Read more)
- 6. J. Non-Cryst. Solids 179, 1-9 (1994) , “The many varieties of E′ centers: a review”, Robert A. WeeksThree varieties of E′ centers with a spin state, S = 1/2, and with a G-tensor, Gx Gy 2.0003, Gz 2.0018, were identified in the early reports on paramagnetic states in irradiated α-quartz. The atomic structure of two of these had an hydrogen ion (proton) in nearby sites and hence... (Read more)
- 7. Surf. Sci. 141, 255-284 (1984) , “X AND K BAND ESR STUDY OF THE Pb INTERFACE CENTRES IN THERMALLY OXIDIZED p-TYPE (001)Si WAFERS AT LOW TEMPERATURES AND INFLUENCE OF MEDIUM-DOSE As+ ION IMPLANTATION”, A. Stesmans, J. Braet, J. Witters, R. F. DekeersmaeckerElectron spin resonance (ESR) experiments have been carried out at cryogenic temperatures (4.2 T 35 K) and room temperatures at 9.0 and 20.9 GHz on the Pb0 and Pb1 (commonly referred to as Pb) spin-active defects residing at the Si/SiO2 interface. The ESR lineshapes were shown to display gaussian... (Read more)
- 8. J. Non-Cryst. Solids 32, 327-338 (1979) , “ELECTRON SPIN RESONANCE AND HOPPING CONDUCTIVITY OF a-SiOx”, E. Holzenkämpfer, F. -W. Richter, J. Stuke, U. Voget-GroteAmorphous SiOx-layers with O < x < 2 have been prepared by evaporation of Si at oxygen pressures of 10−6 … 10−3 mbar. The composition of the samples was determined by proton backscattering. The band gap, derived from optical measurements, increases with rising oxygen... (Read more)
