Origin of the superconductor-insulator transition in disordered two-dimensional films
Alexander Weitzel, Lea Pfaffinger, Animesh Panda +8
Theory predicts the superconductor-to-insulator transition (SIT) to emerge from the competition between Anderson localization, which tends to localize single-particle wavefunctions…

Sharpness of the Berezinskii-Kosterlitz-Thouless transition in ultrathin NbN films
Alexander Weitzel, Lea Pfaffinger, Ilaria Maccari +8
We present a comprehensive investigation of the Berezinskii-Kosterlitz-Thouless (BKT) transition in ultrathin strongly disordered NbN films. Measurements of resistance, current-vol…
