Effective particlehole symmetry breaking, quasi-bond state engineering and optical absorption in graphene based gated dotring nanostructures

We have studied the nature and character switching of relativistic bound states in quantum dotring structures produced by a set of circular concentric metallic gates on a graphene sheet placed over a substrate. The structure consists of an attractive core, a repulsive barrier and an attractive rim r...
