1. A switching element, comprising an input node; an output node; a nanotube channel element having at least one electrically conductive nanotube; a control electrode disposed in relation to the nanotube channel element to controllably form an electrically conductive channel between said input node and said output node, wherein said channel at least includes said nanotube channel element; and wherein said output node is constructed and arranged so that channel formation is substantially unaffected by the electrical state of the output node.
