WebGraphene1is a one-atom-thick, 2D material composed of sp2-hybridized carbon atoms arranged in honeycomb structures. The three sp2orbitals of each carbon atom bond to the surrounding ones via σ bonds, resulting in an ultrahigh mechanical strength of graphene. WebDec 8, 2024 · Despite recent transport studies of ABC-stacked multilayer graphene systems revealed various unusual quantum phenomena which arise from the nearly flat electronic bands, their quantum tunneling properties have rarely been addressed. Here we investigate the local tunneling characteristics of a gapped ABC-stacked trilayer graphene (TLG) and …
