| Summary: | This work is devoted to the study of the effect on the morphology
and on the electronic properties of the graphene plane of defects
of the vacancy type in the form of a vacancy cluster, depending
on the size of the cluster. The optimal configurations of the
arrangement of carbon atoms for the graphene plane from vacancy
clusters are found. The electronic band structure is calculated for
them. The calculations are performed by the ab initio method. The
analysis of the dependence of the morphology of the structure
and some parameters of the electronic structure on the size of the
vacancy cluster is carried out. The results obtained are applicable
to the analysis of the band structure of single-walled carbon tubes
containing vacancy-type defects. |
