Graphene是什么意思
WebApr 2, 2024 · Graphene is an allotrope of carbon that exists as a two-dimensional sheet. One way to think of graphene is as a single layer of graphite, where all the carbons exist in a regular hexagonal array. Being composed of carbon makes graphene a non-metal, but it possesses semiconducting properties that means it often characterized as a quasi-metal.
