1. A method, comprising:
altering a threshold voltage of a transistor by creating a tunneling current that flows through dielectric material located between a quantum dot and into a layer of conductive material, said quantum dot disposed in said dielectric material and located between a carbon nanotube and said layer of conductive material, said transistor having said carbon nanotube electrically coupled between source and drain electrodes, said layer of conductive material forming at least part of said transistor's gate, wherein said electron tunneling current is substantially greater than second tunneling current, if any, between said quantum dot and said carbon nanotube.
