#### **Abstract**

The carbon nanostructures are perspective materials for the future applications. This has two reasons: first, the hexagonal atomic structure, which enables a high molecular variability by placing different kinds of the defects, and second, good electronic prop‐ erties that can be modified for the purpose of the concrete applications with the help of the defects and of the chemical ingredients. Many kinds of the nanostructures are in‐ vestigated. Here, the properties of less common forms are examined—the graphitic nanocone and graphitic wormhole.

**Keywords:** graphene, graphitic wormhole, graphitic nanocone, spin-orbit coupling, zero modes
