スポンサーリンク
概要
- 論文の詳細を見る
A tight-binding type electronic theory is used to calculate the core structureand core energy of both screw and 60' dislocations in Si. The repulsive interactionenergies at short distances are simulated by a Born-Mayer potential. It is shownthat the glide-set dissociated dislocations are more stable than the correspondingshuffle-set perfect dislocation. The calculated core structures and core energiesare compared with those of previous theoretical calculations as well as withavailable experimental results.
