ELECTRON TUNNELING APPARATUS AND ASSOCIATED METHODS

摘要

An apparatus comprising first and second layers of electrically conductive material (304, 307) separated by a layer of electrically insulating material (306), wherein one or both layers of electrically conductive material (304, 307) comprise graphene, and wherein the apparatus is configured such that electrons are able to tunnel from the first layer of electrically conductive material (304) through the layer of electrically insulating material (306) to the second layer of electrically conductive material (307).
