Resumen o descripción
In this work we study the propagation of Dirac electrons through Cantor-like structures in graphene. In concrete,
we are considering structures with magnetic and electrostatic barriers arrange in Cantor-like fashion. The Diraclike
equation and the transfer matrix approach have been used to obtain the transmission properties. We found
self-similar patterns in the transmission probability or transmittance once the magnetic field is incorporated.
Moreover, these patterns can be connected with other ones at different scales through well-defined scaling rules.
In particular, we have found two scaling rules that become a useful tool to describe the self-similarity of our
system. The first expression is related to the generation and the second one to the length of the Cantor-like
structure. As far as we know it is the first time that a special self-similar structure in conjunction with magnetic
field effects give rise to self-similar transmission patterns. It is also important to remark that according to our
knowledge it is fundamental to break some symmetry of graphene in order to obtain self-similar transmission
properties. In fact, in our case the time-reversal symmetry is broken by the magnetic field effects.
