  The graphene and phosphorene nanostructures have a big potential application
in a large area of actuals research in physics. However, their methods of
synthesis still do not allow the production of perfect materials with an intact
molecular structure. In this paper, the occurrence of atomic vacancies was
considered in the edge structure of the zigzag phosphorene and graphene
nanoribbons. For different concentrations of these edge vacancies, their
influence on the metallic properties was investigated. The calculations were
performed for different sizes of the unit cell. Furthermore, for a smaller
size, the influence of a uniform magnetic field was added.
