Superconductivity in low dimensionality has been attracting attentions of many researchers due to its technological and scientific importance. While it is well known that superconductivity is suppressed as the dimensionality is reduced, the conditions and criteria for the dimensionality still remain questionable. Scanning Tunneling Microscopy is a powerful tool for studying both topographies and local electronic structures in nanometer scale. To explore superconductivity at reduced dimensionality, we studied Nb deposits on Si surfaces. Nb, which has the highest superconducting transition temperature among elemental superconductors and has various compounds with even higher transition temperatures, was e-beam evaporated onto Si(111) surface and annealed. The surface was characterized with Scanning Tunneling Microscope (STM) and local electronic structures of the deposited Nb was studied with Scanning Tunneling Spectroscopy (STS).
