Electronic structure in gapped graphene with a Coulomb potential (2009)
Zhu, Wei, Wang, Zhengfei, Shi, Qinwei, Szeto, Kwok-Yip, Chen, Jie, Hou, J. G.
In this paper, we numerically study bound electron states induced by long-range Coulomb impurities in gapped graphene and quasibound states in the supercritical region based on the lattice model. We...
