A striking feature of bilayer graphene is the induction of a significant band gap in the electronic states by the application of a perpendicular electric field1–7. Thicker graphene layers are also highly attractive materials. The ability to produce a band gap in these systems is of great fundamental and practical interest. Both experimental8 and theoretical9–16 investigations of graphene trilayers with the typical ABA layer stacking have, however, revealed the lack of any appreciable induced… CONTINUE READING
