Valence electron structures analysis on relationship of Cu physical or mechanical properties and vacancy

摘要

For the purpose of studying vacancy effect on physics and mechanics property, authors advance a method of calculating mono-vacancy cell valence construction, and get 5 phase construction factors n_A, σ_N σ_V~L , F and α on electron layer. It indicates that vacancy increase electrical resistivity and intensity, and decrease plasticity, which are consistent with experiments. The paper open out the relation between vacancy and physics and mechanics property on electron layer.
