Graphene conductivity vs gold
WebJun 23, 2014 · There are many misconceptions of what graphene actually is. In this case, it is a borderline definition. Graphene, a semi-metal, is a one-atom-thick, crystal-like structure; in essence, an actual ... Webiments in graphene [10–13] completely defied both these expectations: the minimum conductivity, while finite, showed significant sample-to-sample fluc-tuations, and at high carrier density, the conductivity increased linearly with carrier density. While some questions still remain, we now more-or-less understand these trends quantitatively.
