| Abstract: | On the basis of self-consistent calculation of the Bogoliubov-de-Gennes equations on a finite honeycomb lattice with s-wave pairing,the research vestigates effects of chemical potential and different type of disorder on the system.The dependence of pairing potential on the chemical potential and disorder are calculated.The relation between the results and electronic structure is also discussed. |
