| Abstract: | In this paper, the vibrational properties of GaAs-AIAs quasi-crystal superlattice are studied, and compared with those of GaAs-AIAs periodic superlattice as well as those of one-dimensional quasicrystal chains. It is found that the simplified vibrational density of state is in good agreement with the experimental Raman spectra. |
