Calculation of the electronic conductivity of a flat carbon nanostructure based on the model of a hydrogen-like atom

The paper presents the calculation of the electronic conductivity of a graphene sample using the Kubo-Greenwood formula. The ground state of the system is determined by the density functional theory method using the hydrogen-like atomic model. the found wave functions are used for calculating the electronic conductivity in the Kubo-Greenwood formalism. The aim of this work is to check the qualitative correspondence of the results obtained using the model of a hydrogen-like atom with the results in the works of other authors.
