Research Abstract

Low-dimensional superconductivity attracts renewed interests in the fashion of modern nanofabrication techniques. In particular, superconducting nanowires (scNW) have attracted much attention recently on both scientific and applied point of view. We made some progress in such directions, based on graphene.
