Energy Spectra of the Graphene-based Fibonacci Superlattice Modulated by the Fermi Velocity Barriers

Abstract

The energy spectra of the Weyl-Dirac quasi-electrons for this SL are calculated with the help of the transfer matrix method in the continuum model. The Fibonacci quasi-periodic modulation in graphene superlattices with the velocity barriers can be effectively realized by virtue of a difference in the velocity barrier values.
