(color online) (a) Elongation-strain-induced changes of the absorption spectra of 4 × 3 rectangular C2O nanostructures. Fourier transform of the induced charge density for rectangular C2O nanostructures 4 × 3; ((b) and (c)) Polarization direction is along the armchair-edge at the energy points 7.15 eV and 5.85 eV, respectively, and the values of η are both 0, 9%. |
