摘要: Introducing a model nanostructured chain, we study the electronic properties of one-dimensional ordered nanostructured solids in terms of an exact Green's function renormalization-group approach, It is found that two kinds of electronic state, namely localized state and extended statess exist in certain energy regions. As the grain size decreases, the energy regions corresponding to the extended quantity, as well as the gaps, become wider, while the number of the isolated peaks decreases. Furthermore, the appearances of isolated peaks are mainly, due to the modulations of the interface sites.
