Prediction of stability for carbon nanotori

At the present time carbon nanostructures are the main functional material for the development of electronic devices of broad applications. One of the most perspective for practical application forms of carbon nanostructures are nanotori. This paper presents results of prediction the stability of toroidal structures using computer modeling methods. The stability of carbon nanotori are determined by scanning of the local stresses map. Obtained results showed that the highest stability is characterized for carbon nanotori (13, 0) formed by the folding of a zigzag carbon nanotube. These nanotori are characterized by the lowest enthalpy of structure formation (101 eV).
