Optical absorption spectrum of small fragments of a carbon plane with topological defects
Energy spectra of small fragments of a carbon plane both ideal and containing topological defects such as vacancies and the Stone-Wales deformation, are calculated in the frame of the Hubbard model in the approximation of static fluctuations. The optical absorption spectra of ideal and defective fragments are simulated; the change in the shape of the absorption curve with increasing vacancy concentration is analyzed. The dependences of the energy gap on the type of defect configuration and concentration are obtained.
