Seed‐Layer‐Free Atomic Layer Deposition of Highly Uniform
Atomic layer deposition (ALD) is the method of choice to obtain uniform insulating films on graphene for device appliions. Owing to the lack of out‐of‐plane bonds in the sp 2 lattice of graphene, nucleation of ALD layers is typically promoted by functionalization treatments or predeposition of a seed layer, which, in turn, can adversely affect graphene electrical properties.
