Figure 5From: Thinning and functionalization of few-layer graphene sheets by CF4 plasma treatmentBand structures and densities of states of F- and CF 3 -functionalized graphene sheets. ( a) Band structure and ( b) density of states of a F-functionalized graphene sheet. ( c) Band structure and ( d) density of states of a CF3-functionalized graphene sheet. The Fermi level is set at 0 eV.Back to article page
