The calculations were performed at the LCCA-CCE of the Universidade de São PauloAbstract: We investigated core properties of dislocations in zinc-blende semiconductors using ab initio total energy calculations. The core reconstruction energy of partial dislocations was found to scale almost linearly with the experimental dislocation activation energy. The electronic band structure related to dislocation cores was also determined. In an unreconstructed core, the gap states comprise a half-filled one-dimensional band, which splits up in bonding and antibonding states upon reconstruction. The energy states which lie in the electronic gap come from the cores of ß partials, while those related to a partials remain resonant in the valence bandFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPCONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFechadoYamada Conference on Shallow-Level Centers in Semiconductors (54. : 24 a 27 de Setembro de 2000 : Awaji Island, Japão)UNIVERSIDADE ESTADUAL DE CAMPINASAntonelli, Alex, 1954-2001info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://hdl.handle.net/20.500.12733/1664973ANTONELLI, Alex.
