Abstract
The generation of a gap in graphene has potentially useful implications for the production of electrical components.
Experimentally the gapped (insulating) state has never been observed.
Theorists would like to provide information on how a gap could be produced.
We study the effect on the critical coupling of straining a graphene lattice.
We work with a low energy effective theory obtained by considering a tight-binding Hamiltonian expanded around the Dirac points in momentum
space.
