▎ 摘  要

The induced charge density, rho(ind)(r), generated in graphene by the potential well of the finite radius R is considered. The result for rho(ind)(r) is derived for large distances rR. We also obtained the induced charges outside of the radius rR and inside of this radius for subcritical and supercritical regimes. The consideration is based on the convenient representation of the induced charge density via the Green's function of electron in the field.
