摘 要:The electronic spectra of one-dimensional nanostructured systems are calculated within the pure hopping model on the tight-binding *** means of the renormalization group Green s function method,the dependence of the density of states on the distributions of nanoscaled grains and the changes of values of hopping integrals in nanostructured systems are *** is found that the frequency shifts are dependent rather on the changes of the hopping integrals at nanoscaled grains than the distribution of nanoscaled grains.
