Quantum-mechanical study of effect of lattice defects on surface properties and copper activation of sphalerite surface CHEN Jian-hua(陈建华)1, CHEN Ye(陈 晔)2, LI Yu-qiong(李玉琼)2 1. College... on the copper activation of sphalerite were investigated. Calculated results indicate that both Fe and Mn impurities narrow the band gap of sphalerite surface and lead to the Fermi level shifting......
