Graphene conduction
WebThe high electronic conductivity is due to low defect density in crystal lattice. The defects present in crystal act as scattering sites and hinder charge transport by decreasing the electron mean free path. The pristine graphene is defect free, and its conductivity must be affected by some more extrinsic factors. WebGraphene is a two-dimensional structure of carbon atoms. Single-layer graphene consists of only one layer of carbon atoms. A carbon atom has six electrons occupying the 1 s2, 2 …
