Abstract: A graphene screening and separation method comprises the following steps. At least one pair of electrodes and an energy barrier layer is provided, wherein the pair of electrodes is a first electrode and a second electrode, and the energy barrier layer is formed on the first electrode. The pair of electrodes and the energy barrier layer are covered with a graphene suspension. When a graphene sheet in the graphene suspension materially couples the second electrode and the energy barrier layer and is located above the first electrode, a bias voltage between the first electrode and the second electrode of the pair of electrodes is changed and a corresponding tunneling current is measured. Screening and separation are performed by using differential conductance (i.e., the derivative of the tunneling current with respect to the bias voltage) of different layers of graphene.
