A method for fabricating an electron tunneling device on a substrate includes forming a first non-insulating layer on the substrate and providing a first amorphous layer. The method further includes the steps of providing a second layer, and forming a second non-insulating layer and providing an antenna structure connected with the first and second non-insulating layers. The second layer of material is configured to cooperate with the first amorphous layer such that the first amorphous layer and the second layer of material together serve as a transport of electrons between and to the first and second non-insulating layers, and the transport of electrons includes, at least in part, transport by means of tunneling.
