Tunable dichroism and optical absorption of graphene by strain engineering
M. Oliva-Leyva, Gerardo G. Naumis
We theoretically study the transmittance for normal incidence of linearly polarized light between two media separated by a strained graphene monolayer. We analytically characterize…
Spectral butterfly, mixed Dirac-Schrödinger fermion behavior and topological states in armchair uniaxial strained graphene
Pedro Roman-Taboada, Gerardo G. Naumis
An exact mapping of the tight-binding Hamiltonian for a graphene's nanoribbon under any armchair uniaxial strain into an effective one-dimensional system is presented. As an applic…
Generalizing the Fermi velocity of strained graphene from uniform to nonuniform strain
M. Oliva-Leyva, Gerardo G. Naumis
The relevance of the strain-induced Dirac point shift to obtain the appropriate anisotropic Fermi velocity of strained graphene is demonstrated. Then a critical revision of the ava…
Mapping of strained graphene into one-dimensional Hamiltonians: quasicrystals and modulated crystals
Gerardo G. Naumis, Pedro Roman-Taboada
The electronic properties of graphene under any arbitrary uniaxial strain field are obtained by an exact mapping of the corresponding tight-binding Hamiltonian into an effective on…
