- 1. Nucl. Instrum. Methods Phys. Res. B 141, 566-574 (1998) , “Defect formation in amorphous SiO2 by ion implantation: Electronic excitation effects and chemical effects”, H. Hosono, N. MatsunamiIntrinsic defect formation in amorphous (a-) SiO2 by ion implantation was examined with emphasis upon electronic excitation effects and chemical reaction effects. 10 MeV proton beam and boron beam irradiated silica platelets to examine electronic excitation effects and chemical reaction effects. In... (Read more)
- 2. Phys. Rev. Lett. 80, 317-320 (1998) , “Experimental Evidence for Frenkel Defect Formation in Amorphous SiO2 by Electronic Excitation”, H. Hosono, H. Kawazoe, N. MatsunamiConcentrations of defects in amorphous SiO2 created by implantation of 10 MeV protons were examined. The depth profile of Si-Si bonds, E? centers, or peroxy radicals (PORs) was close to that of electronic energy loss. Interstitial O2 molecules were identified and... (Read more)
- 3. 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)
