There are numerous forms of carbon structures, starting from diamond, graphite, graphene and others. Other forms of carbon structures are possible, it is expected that they can lead to interesting applications. The present article is devoted to the study of the electronic properties of a not synthetized yet metastable form of carbon-penta-graphene. A nanoribbon geometry is considered in which the geometric quantization leads to the appearance of the band gap, the width of which may be adjusted. The system has additional defects (vacancies) and can be subjected to external electric fields. In this way, a desired band structure, like e.g. transition from direct to skew band near the Fermi level, can be achieved. Although penta-graphene is still a hypothetical material, this article can stimulate further research towards the successive synthesis of penta-graphene.
