Graphene Layers on Conductive SiC
Graphene layers grown on a conductive SiC substrate exhibit thickness-dependent electronic properties and surface potential variations between regions.
Heterodyne KPFM directly visualizes these layer-dependent potential contrasts, enabling clear electrical differentiation of graphene domains beyond topographic features.
