Query: Destruction of superconductivity through phase fluctuations in ultrathin
  a-MoGe films   We investigate the evolution of superconductivity with decreasing film
thickness in ultrathin amorphous MoGe (a-MoGe) films using a combination of
sub-Kelvin scanning tunneling spectroscopy, magnetic penetration depth
measurements and magneto-transport measurements. We observe that
superconductivity is strongly affected by quantum and classical phase
fluctuations for thickness below 5 nm. The superfluid density is strongly
suppressed by quantum phase fluctuations at low temperatures and evolves
towards a linear-T dependence at higher temperatures. This is associated with a
rapid decrease in the superconducting transition temperature, Tc, and the
emergence of a pronounced pseudogap above Tc. These observations suggest that
at strong disorder the destruction of superconductivity follows a Bosonic route
where the global superconducting state is destroyed by phase fluctuations even
though the pairing amplitude remains finite.
