- 1. Phys. Rev. B 75, 193203 (2007) , “Hf defects in c-Si and their importance for the HfO2/Si interface: Density-functional calculations”, Wanderlã L. Scopel, Antônio J. R. da Silva, and A. FazzioWe have studied, using ab initio density functional theory calculations, substitutional and interstitial Hf impurities in c-Si, for various charge states. Our results indicate that (1) the tetrahedral interstitial defect is energetically more favorable than the substitutional and (2)... (Read more)
- 2. Phys. Rev. B 75, 193201 (2007) , “Compensating point defects in 4He+-irradiated InN”, F. Tuomisto, A. Pelli, K. M. Yu, W. Walukiewicz, and W. J. SchaffWe use positron annihilation spectroscopy to study 2 MeV 4He+-irradiated InN grown by molecular-beam epitaxy and GaN grown by metal-organic chemical-vapor deposition. In GaN, the Ga vacancies act as important compensating centers in the irradiated material, introduced at a... (Read more)
- 3. Phys. Rev. B 75, 075316 (2007) , “Theoretical investigation of a Mn-doped Si/Ge heterostructure”, J. T. Arantes, Antônio J. R. da Silva, A. Fazzio, and A. AntonelliWe investigate, through ab initio density-functional theory calculations, the electronic and structural properties of neutral Mn impurities at tetrahedral interstitial and substitutional sites in both Si and Ge layers of a Si/Ge heterostructure. We conclude that substitutional Mn at the Ge... (Read more)
