The C•Si•O•Si (•C) Four-Member Ring and the Si-G15 Centre
Based on geometry optimisation molecular cluster calculations employing the MINDO/3 method, we have concluded that the interstitial-carbon interstitial-oxygen complex in silicon has a C•Si•O•Si (•C) four-member ring structure as the most stable state. Our conclusion is similar to that of Jones and Oberg who carried out a LDF (local density functional) pseudopotential calculation on a similar molecular cluster. The computed properties of our four-member ring structure are compared with those of the Si-G15 defect.
