Abstract
By means of atomistic Tight Binding simulations, we study heterostructures made of an armchair BN nanoribbon sided by two armchair graphene ribbons where a high band gap can be opened. We show that this band gap can be significantly suppressed by applying a relatively weak transverse electric field. This effect can be used to strongly enhance the on/off current ratio higher in graphene transistors.
