Tamm minibands in graphene-based planar superlattices

The Tamm minibands in planar superlattices composed of graphenes with different Fermi velocities and energy gaps have been investigated. It is shown that Tamm minibands arise only in the case of intersection of the dispersion curves of charge carriers in different superlattice regions.
