Abstract :
The possibility of increasing the superconducting transition temperature (Tc) by means of varying the Fermi-energy level (FEL) in quantum wires (QWR) is considered. It is shown that this can be realized if there is coincidence of the FEL with a quantum energy level in the QWR. Procedures for achieving such a coincidence in carbon nanotubes are proposed, first through adjustment of the FEL by means of varying the electrical field in the nanotube, and secondly by changes in the geometry and size of the nanotube itself. Some technological pathways to achieving FEL and quantum energy level coincidence are considered.
