Lattice of superconducting multilayer nanotubes as ideal high-temperature superconductor

Combining Little's and Ginzburg's ideas with recent progress in nanotubes research, a novel type of material is advanced as a perspective high-Tc superconductor based on a close packed lattice of quasi-1D superconducting nanotubes. It is suggested that superconducting coaxial multilayer nanotubes of the correlation length in diameter provide an ideal and natural trap for pinning of the Abrikosov vortex. The nanotube should be a layered superconductor, such as LuNiBC. The mechanism of superconductivity was proposed and substantiated quantitatively on the basis of a whispering mode, which is shown to be responsible for a strong enhancement of electron-phonon interaction and for an increase of critical temperature. Nanocomposites built from such quasi-1D nanotubes, when coinciding with the vortex lattice, provide ideal conditions for the pinning, resonance, distortion, ordering, and Little-Parks effects, the joint action of which is suggested to result in a synergetic effect increasing the superconductivity. Such quasi-1D nanotubular crystal could be synthesized by a template approach using a zeolite-like membrane. (Author)
