Efficient and scalable high-quality graphene nanodot fabrication through confined lattice plane electrochemical exfoliation.

Reported is a confined lattice plane electrochemical exfoliation method that exploits the electrochemical reaction of face (basal) or side (edge) planes of highly oriented pyrolytic graphite (HOPG) while other planes are blocked using wax, based on the anisotropy of HOPG for efficient and effective fabrication of graphene nanodots with uniform size distribution.
