Abstract: The electronic structure of quasi-one-dimensional disordered system is studied by the computation of the density of electronic states with the help of the negative eigenvalue theory. The localization of electronic states and the distribution zone of the system energy are discussed to the parameters of system size and the disordered degree of diagonal and non-diagonal elements. The electronic localized states are increased with the enhancing of the diagonal disordered degree and the distribution zone of the system energy is widened with the enhancing of the non-diagonal disordered degree.

Key words: Quasi-one dimensional, Disordered system, Density of electronic state
