Tunability of the Berry phase in gapped graphene
Andrea Urru, Giulio Cocco, Vincenzo Fiorentini
When a gap of tunable size opens at the conic band intersections of graphene, the Berry phase does not vanish abruptly, but progressively decreases as the gap increases. The phase…
Vibrational stability of graphene under combined shear and axial strains
Giulio Cocco, Vincenzo Fiorentini
We study the vibrational properties of graphene under combined shear and uniaxial tensile strain using density-functional perturbation theory. Shear strain always causes rippling i…
Reply to "Comment on Gap opening in graphene by shear strain''
Giulio Cocco, Emiliano Cadelano, Luciano Colombo
In reply to the Comment by Ramasubramaniam regarding our article [Phys. Rev. B {\bf 81}, 241412(R) (2010)] we clarify that our results are indeed valid provided that out-of-plane a…
Gap opening in graphene by shear strain
Giulio Cocco, Emiliano Cadelano, Luciano Colombo
We exploit the concept of strain-induced band structure engineering in graphene through the calculation of its electronic properties under uniaxial, shear, and combined uniaxial-sh…
