- 1. J. Appl. Phys. 99, 043509 (2006) , “Influence of metal trapping on the shape of cavities induced by high energy He+ implantation”, R. El Bouayadi, G. Regula, M. Lancin, B. Pichaud, and M. DesvignesIn He implantation induced cavities highly contaminated with metals (Au, Ni, Pt) we found that, when no three-dimensional structure is observed, the shape of the cavities can be strongly modified depending on the nature of the metal and on its trapped quantity. The equilibrium shape of cavities is... (Read more)
- 2. Phys. Rev. B 74, 165404 (2006) , “Density functional study of gold atoms and clusters on a graphite (0001) surface with defects”, Jaakko Akola and Hannu HäkkinenAdsorption of gold atoms and clusters (N=6) on a graphite (0001) surface with defects has been studied using density functional theory. In addition to perfect graphite (0001), three types of surface defects have been considered: a surface vacancy (hole), a pyridinelike defect comprising three... (Read more)
- 3. Appl. Catalysis A 213, 173-177 (2001) , “In situ electron paramagnetic resonance (EPR) study of surface oxygen species on Au/ZnO catalyst for low-temperature carbon monoxide oxidation”, Zhengping Hao, Liangbo Fen, G. Q. Lu, Jianjun Liu, Lidun An and Hongli WangSome paramagnetic superoxide ions detectable by electron paramagnetic resonance (EPR) can be generated on Au/ZnO catalyst by oxygen adsorption at room temperature as well as at 553 K. In both the cases, the O2− ions are present on the catalyst surface. The disappearance of the O2−... (Read more)
- 4. Physica B 302-303, 233-238 (2001) , “Complexes of Gold and Platinum with Hydrogen in Silicon”, P. T. Huy and C. A. J. AmmerlaanThree centers that involve gold or platinum and hydrogen have been observed in n-type hydrogenated silicon by electron paramagnetic resonance. The first two centers, labeled Si-NL63 and Si-NL64, were detected in the gold-doped samples revealing hyperfine interaction with two gold atoms for the... (Read more)
- 5. phys. stat. sol. (b) 221, 625-631 (2000) , “Identification of the Gold-Lithium Defect L1 in Silicon with the Trigonal Centre Au2--(Li+)3 by Electrical, Optical and Magnetic Resonance Spectroscopy”, B. Langhanki, J. ?M. SpaethN-type silicon doped with gold and lithium was investigated by Electron Paramagnetic Resonance (EPR) and Deep Level Transient Spectroscopy (DLTS), using two sets of samples with different defect concentrations of both gold and lithium. Photoluminescence (PL) on both sets of samples allowed to... (Read more)
- 6. Semicond. Sci. Technol. 10, 977 (1995) , “EPR and ENDOR Observation of Orthorhombic Au-Li and Pt-Li Pairs in Silicon: on the Problem of the Observation of Isolated AuSi0 with Magnetic Resonance”, S. Greulich-Weber, P. Alteheld, J. Reinke, H. Weihrich, H. Overhof, J. M. Spaeth.We report the observation of orthorhombic Au-Li and Pt-Li pairs in Si using EPR and ENDOR techniques and also MCDA spectroscopy. The EPR spectra alone could be mistaken as being due to orthorhombic isolated point defects and ENDOR is required to detect the Li partner of the pair. Comparison of the... (Read more)
- 7. phys. stat. sol. (b) 119, K117 (1983) , “Gold-related EPR centres of low symmetry in silicon”, M. Höhne.The most important gold-related centre in silicon works incognito: It produces levels which are well known /1/. The acceptor level EC-0.55 eV and the donor level EV+0.35 eV are caused by different states of the same defect, as was als orecentlr affirmed /2, 3/. This defect is... (Read more)
- 8. phys. stat. sol. (b) 109, 525 (1982) , “Electron Paramagnetic Resonance of Gold in Silicon. II. Cluster Centres”, M. Höhne.The interpretation of the EPR spectrum suggests two alternative models: five gold atoms or three gold atoms with two boron atoms, respectively, form a cluster occupying lattice sites and adjacent interstitial sites. This cluster tends to further precipitation. Both of the paramagnetic gold-related... (Read more)
- 9. phys. stat. sol. (b) 99, 651 (1980) , “Electron Paramagnetic Resonance of Gold in Silicon.I. Single Atoms; Strong Nuclear Quadrupole Effect”, M. Höhne.In Si : Au rapidly quenched two centres are observed by EPR, the first of which is investigated in this paper. The spectrum is characterized by a dominating Zeeman interaction and by a nuclear quadrupole interaction large compared to the hyperfine interaction. Passage conditions depend on the... (Read more)
- 10. Phys. Rev. 117, 1287 (1960) , “Magnetic Moment of Au197”, H. H. Woodbury, G. W. Ludwig.Chromium-gold and maganese-gold impurity pairs in silicon have been observed by electron spin resonance techniques. Electron-nuclear double resonance studies of the gold hyperfine structure lead to a value of 0.1439?0.0004 nm for the magnetic moment of Au197. (Read more)
