Abstract
We report the evolution of upper critical field (Hc2) and the Ginzburg‐Landau coherence length (ξGL) with disorder, in 3 dimensional homogeneously disordered epitaxial NbN thin films. The effective disorder in NbN is controlled from moderately clean limit down to Anderson metal‐insulator transition by changing the deposition conditions. We observe that the Ginzburg‐Landau coherence length increases by a factor of 2 as the superconducting critical temperature (Tc) decreases from ∼16 K to ∼2 K.
