Patent ID: 7652342

Claim:
A nanotube transfer device, comprising: a first output node connected to a first network; a second output node connected to a second network; a nanotube channel element including at least one electrically conductive nanotube, each end of said nanotube channel element being pinned in a fixed position by an insulating structure, said nanotube channel element being electrically isolated by the insulating structure and not in physical contact with either of said first output node or said second output node thereby forming an OFF state of the device; and a control structure having one control electrode disposed in relation to the nanotube channel element to controllably form an electrically conductive channel between said first output node and said second output node through said nanotube channel element, thereby forming an ON state of the device wherein an arbitrary signal is transferred between said first output node and said second output node; wherein the OFF state of the device is effectuated by the nanotube channel element having a first operating voltage range and wherein the ON state of the device is effectuated only by the control electrode having a second operating voltage range, and wherein an upper operating voltage of said second operating voltage range exceeds an upper operating voltage of said first operating range by at least an amount sufficient to form the electrically conductive channel.
