Atomic collapse in gapped graphene: lattice and valley effects
Jing Wang, Xiaotai Wu, Wen-Sheng Zhao +3
We study the atomic collapse phenomenon in and valley of gapped graphene. Bound states induced by Coulomb impurity in the gap turn into atomic collapse resonances as the c…

Charged vacancy in graphene: interplay between Landau levels and atomic collapse resonances
Jing Wang, Wen-Sheng Zhao, Yue Hu +2
The interplay between a magnetic field and the Coulomb potential from a charged vacancy on the electron states in graphene is investigated within the tight-binding model. The Coulo…
