Electronic structure of spontaneously strained graphene on hexagonal Boron Nitride
Pablo San-Jose, Ángel Gutiérrez, Mauricio Sturla +1
Hexagonal Boron Nitride substrates have been shown to dramatically improve the electric properties of graphene. Recently, it has been observed that when the two honeycomb crystals…
Spontaneous Strains and Gap in Graphene on Boron Nitride
Pablo San-Jose, Ángel Gutiérrez, Mauricio Sturla +1
The interaction between a graphene layer and a hexagonal Boron Nitride (hBN) substrate induces lateral displacements and strains in the graphene layer. The displacements lead to th…
Generalized effective hamiltonian for graphene under non-uniform strain
Juan L. Mañes, Fernando de Juan, Mauricio Sturla +1
We use a symmetry approach to construct a systematic derivative expansion of the low energy effective Hamiltonian modifying the continuum Dirac description of graphene in the prese…
Space dependent Fermi velocity in strained graphene
Fernando de Juan, Mauricio Sturla, Maria A. H. Vozmediano
We resolve some apparent discrepancies between two different models for curved graphene: the one based on tight binding and elasticity theory, and the covariant approach based on q…
