Changes of self-similarity in superlattices through the gaps distribution

Two properties related with the geometrical distributions of gaps into the fractal structure are investigated. We discussed them using a matricial met hod; however, other computational methods can also be used. The first prope rty is the intrinsic periodicity, related with the width of fine structure, which is included in the reflectance distribution. The second property is related with the change in the geometry itself when the superlattice gaps o ccupy different positions into the structure. We define a similarity functi on to quantify the last consideration and we applied it to Canter superlatt ices with two different dimensions.
