The critical effect of disorder on the two-dimensional (2D) surface superconductor Si(111)-($\sqrt{7}\times\sqrt{3}$)-In is clarified by comparing two regions with different degrees of disorder. Low-temperature scanning tunneling microscopy measurements reveal that superconductivity is retained in the less disordered region, judging from the characteristic differential conductance ($dI/dV$) spectra and from the formation of vortices under magnetic fields. In striking contrast, the absence of… Expand

Electronic and transport properties of Pb-dense reconstructions on Si(100)
Abstract Electronic and transport properties of the dense Pb/Si(100) reconstructions, 2 × 1-Pb with 1.5 ML (monolayer) of Pb and c(4 × 4)-Pb with ∼ 1.875 (15/8) ML of Pb, have been explored usingExpand
Phonon limited superconducting correlations in metallic nanograins
TLDR
It is demonstrated that strong e-ph scattering smears the peak structure in the electronic density-of-states of a metallic grain and enhances the electron mass, and thereby limits the highest Tc achievable by quantum confinement. Expand
