| dc.description | The authors investigated the electronic properties of a one-dimensional on-site disordered model, which is constructed from a linear composition of two binary compounds with random periods, having two hybridizing bands on every site. Using the improved Dean method and the second-moment formulae, the effects of both disorder and hybridization on the energy spectrum and the property of wavefunction are studied. The results show that the appearance of some special peaks in the spectrum is due to a particular arrangement of atoms that occurs randomly and the effect of disorder on the energy spectrum decreases in the case of large hybridization. The delocalization of the wavefunctions tends to be enhanced as the hybridization increases. When the hybridization becomes larger than a critical value, some delocalized wavefunctions appear. |
