Interaction between dangling bonds in vacancy-defects in silicon

  • 1. Sao Paulo Univ. (Brazil). Inst. de Fisica

Description

The 'defect-molecule' model in the simplest scheme (without configuration interaction) is reviewed and the concept of 'delocalized dangling-bonds' is explorated in the study of the interaction between the unsaturated hybrids of the mono and divacancy in silicon. The 'defect-molecule' hamiltonian is written in parametric form, and the parameters are extracted from full self-consistent calculations for both systems carried out through the MS-Xα molecular cluster model.

Abstract (Portuguese)

Faz-se uma breve revisao do esquema mais simplificado do modelo da 'molecula de defeito' (sem interacao de configuracao), e explora-se o conceito de orbital flutuante 'deslocalizado' no estudo da interacao dos hibridos nao saturados da mono e divacancia em silicio. O hamiltoniano da 'molecula de defeito' e escrito em forma parametrica, sendo os parametros entao extraidos de calculos autoconsistentes completos para os dois sistemas, realizados atraves do modelo de aglomerados moleculares no formalismo do Espalhamento Multiplo - Xα.
