Tunable band gaps in bilayer graphene-BN heterostructures
Ashwin Ramasubramaniam, Doron Naveh, ELias Towe
We investigate band-gap tuning of bilayer graphene between hexagonal boron nitride sheets, by external electric fields. Using density functional theory, we show that the gap is con…

Comment on "Gap opening in graphene by shear strain"
Ashwin Ramasubramaniam
G. Cocco, E. Cadelano, and L. Colombo [Phys. Rev. B 81, 241412(R) (2010)] have suggested that combinations of shear and uniaxial strain can be used to open a band gap in graphene a…
