The transmittance is studied, using the transfer matrix method, for various multi-barrier systems. The calculations are made in the framework of effective mass theory. The transmittance is calculated for one system increasing the number of layers (generations). The systems are built by mixing a Cantor-like potential with a superlattice. Both cases, barriers and wells, for the Cantor-like potential, are considered to compare the variations between the known superlatice and the proposed mixed system. The resulting potential is as follows, first a superlattice, next a Cantor and finally another superlattice. Another interesting feature is to study the effect of the width and number of layers for the super lattices. The fractal dimension of the transmittance and the potential is calculated, using an image processing technique, to determine if some correlation exists between the fractality of the potential and the fractality of the transmittance.
