- 1. Phys. Rev. B 75, 045211 (2007) , “Ab initio supercell calculations on aluminum-related defects in SiC”, A. Gali, T. Hornos, N. T. Son, E. Janzén, and W. J. ChoykeAb initio supercell calculations of the binding energies predict complex formation between aluminum and carbon interstitials in SiC. In high-energy implanted SiC aluminum acceptor can form very stable complexes with two carbon interstitials. We also show that carbon vacancy can be attached to... (Read more)
- 2. Appl. Phys. Lett. 88, 182903 (2006) , “Effects of Al addition on the native defects in hafnia”, Q. Li, K. M. Koo, W. M. Lau, P. F. Lee, J. Y. Dai, Z. F. Hou, X. G. GongTwo occupied native defect bands are experimentally detected in pure HfO2. The density of states of band one in the middle of the band gap reduces drastically with the Al addition, while that of band two slightly above the valence-band maximum remains rather unaffected. We attribute the... (Read more)
- 3. Phys. Rev. B 71, 035213 (2005) , “Possibility for the electrical activation of the carbon antisite by hydrogen in SiC”, A. Gali, P. Deák, N. T. Son, and E. JanzénCalculations predict the carbon antisite to be the most abundant intrinsic defect in silicon carbide in a wide range of doping. The isolated carbon antisite is, however, optically and electronically inactive, therefore, difficult to observe by usual experimental techniques. However, CSi... (Read more)
- 4. Phys. Rev. B 69, 233202 (2004) , “Diffusion of hydrogen in perfect, p-type doped, and radiation-damaged 4H-SiC”, B. Aradi, P. Deák, A. Gali, N. T. Son, E. JanzénThe diffusion of interstitial atomic hydrogen in 4H-SiC was investigated theoretically, using the local density approximation of density functional theory. We have found that the diffusion barrier in the perfect crystal is 0.6 eV. Comparing this value with the calculated zero point vibration... (Read more)
- 5. Physica B 302-303, 249-256 (2001) , “Hydrogen-Enhanced Clusterization of Intrinsic Defects and Impurities in Silicon”, B. N. Mukashev, Kh. A. Abdullin, Yu. V. Gorelkinskii, M. F. Tamendarov and S. Zh. TokmoldinFormation of intrinsic and impurity defect complexes in hydrogenated monocrystalline silicon is studied. Hydrogen was incorporated into samples by different ways: either by proton implantation at 80 and 300 K, or by annealing at 1250°C for 30–60 min in a sealed quartz ampoule containing... (Read more)
- 6. Mater. Sci. Eng. B 58, 171-178 (1999) , “Self-Interstitial Related Reactions in Silicon Irradiated by Light Ions”, B. N. Mukashev, Kh. A. Abdullin, Yu. V. Gorelkinskii and S. Zh. TokmoldinRecent deep level transient spectroscopy (DLTS), electron paramagnetic resonance (EPR) and infrared (IR) spectroscopy data on interactions of self-interstitial with carbon, aluminium, oxygen and hydrogen in silicon irradiated by light ions are reviewed. Self-interstitial behaviour in silicon was... (Read more)
- 7. phys. stat. sol. (a) 168, 73 (1998) , “Self-Interstitials in Silicon Irradiated with Light Ions”, B. N. Mukashev, Kh. A. Abdullin, Yu. V. Gorelkinskii.The behavior of self-interstitials in silicon which was irradiated with light ions (protons and -particles) and electrons was explored by monitoring known impurity interstitial centers (Ci, Ali, (Si-O)i) with deep level transient spectroscopy (DLTS) and electron...

- 8. Phys. Rev. B 1, 1908 (1970) , “Electron Paramagnetic Resonance of the Aluminum interstitial in Silicon”, Keith L. BrowerElectron-paramagnetic-resonance spectra of the Al++ interstitial (Si-G18) produced in aluminum-doped (p-type) silicon by room temperature or 4°K electron irradiations are presented and show that the Al++ is located in the tetrahedral interstitial site. The hyperfine... (Read more)
