- 1. Phys. Rev. Lett. 98, 015501 (2007) , “First-Principles Simulations of Boron Diffusion in Graphite”, I. Suarez-Martinez, A. A. El-Barbary, G. Savini, and M. I. HeggieBoron strongly modifies electronic and diffusion properties of graphite. We report the first ab initio study of boron interaction with the point defects in graphite, which includes structures, thermodynamics, and diffusion. A number of possible diffusion mechanisms of boron in graphite are... (Read more)
- 2. Phys. Rev. B 74, 144432 (2006) , “Role of defects in ferromagnetism in Zn1−xCoxO: A hybrid density-functional study”, C. H. PattersonExperimental studies of Zn1−xCoxO as thin films or nanocrystals have found ferromagnetism and Curie temperatures above room temperature and that p- or n-type doping of Zn1−xCoxO can change its magnetic...

- 3. Phys. Rev. Lett. 97, 255902 (2006) , “Atomistic Mechanism of Boron Diffusion in Silicon”, Davide De Salvador, Enrico Napolitani, Salvatore Mirabella, Gabriele Bisognin, Giuliana Impellizzeri, Alberto Carnera, and Francesco PrioloB diffuses in crystalline Si by reacting with a Si self-interstitial (I) with a frequency g and so forming a fast migrating BI complex that can migrate for an average length λ. We experimentally demonstrate that both g and λ strongly depend on the free hole... (Read more)
- 4. Phys. Rev. B 70, 115203 (2004) , “Different roles of carbon and silicon interstitials in the interstitial-mediated boron diffusion in SiC”, Michel Bockstedte, Alexander Mattausch, and Oleg PankratovThe interstitial and vacancy mediated boron diffusion in silicon carbide is investigated with an ab initio method. The boron interstitials in p-type and n-type materials are found to be far more mobile than the boron-vacancy complexes. A kick-out mechanism and an interstitialcy... (Read more)
- 5. Phys. Rev. B 69, 233202 (2004) , “Diffusion of hydrogen in perfect, p-type doped, and radiation-damaged 4H-SiC”, B. Aradi, P. De?k, A. Gali, N. T. Son, E. Janz?nThe 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)
- 6. Phys. Rev. B 44, 11486-11489 (1991) , “Reorientation of the B-H complex in silicon by anelastic relaxation experiments”, G. Cannelli, R. Cantelli, M. Capizzi, C. Coluzza, F. Cordero, A. Frova, A. Lo PrestiThe elastic energy loss between 60 and 300 K was measured in SiBxHy at frequencies between 2.4 and 32 kHz. A single-time relaxation process appears in the neighborhood of 130 K, which is due to the stress-induced jumps of H around B, with a relaxation time... (Read more)
- 7. Phys. Rev. B 39, 10791-10808 (1989) , “Theory of hydrogen diffusion and reactions in crystalline silicon”, Chris G. Van de Walle, P. J. H. Denteneer, Y. Bar-Yam, and S. T. PantelidesThe behavior of hydrogen in crystalline silicon is examined with state-of-the-art theoretical techniques, based on the pseudopotential-density-functional method in a supercell geometry. Stable sites, migration paths, and barriers for different charge states are explored and displayed in total-energy... (Read more)
- 8. J. Appl. Phys. 35, 379-397 (1964) , “Diffusion and Solubility of Copper in Extrinsic and Intrinsic Germanium, Silicon, and Gallium Arsenide”, R. N. Hall and J. H. RacetteThe solubilities of substitutional and interstitial copper (Cus and Cui) have been measured in intrinsic and extrinsic n- and p-type Ge, Si, and GaAs, using Cu64. These measurements show that Cus is a triple acceptor in... (Read more)
