摘要：
Electronic properties of a class of one-dimensional quasiperiodic systems are studied by the extended Kohmoto-Kadanoff-Tang (KKT) renormalization-group method. The employed models are tight-binding diagonal and off-diagonal models. It is showed that the energy spectra of the quasiperiodic systems are Cantor-like, namely the spectra are self-similar and the energy gaps are every-where dense on the real E-line. © 1990 Springer-Verlag.
