▎ 摘  要

We calculate and analyze, within a model that allows to obtain an analytical approximation using the method of Jacobi matrices, the electronic spectra of graphene with impurity atoms, especially with boron substitutional impurity. We present analytical expressions for the conditions of the existence of electronic local discrete levels due to the presence of a substitutional impurity in graphene. (C) 2012 Elsevier Ltd.
