We study the electronic structure of a (001) face centered cubic quasi-periodic superlattice within a tight binding model using the transfer matrix method and a pertubative approach. The band gaps are found to vary strongly within the two dimensional Brillouin zone and there are a few eigenvalues for each k//1//1 for which the eigenstates appear to be extended in the quasi-periodic direction also.
