It introduces a model for bound states in graphene with short-range impurities, accounting for various local perturbations.

Findings

Bound states depend on impurity type and strength

Abstract

Bound electron states in impure graphene are considered. Short-range perturbations for defect and impurities of the types "local chemical potential" and "local gap" are taken into account.
