Query: Robust pseudogap across the magnetic field driven superconductor to
  insulator-like transition in strongly disordered NbN films   We investigate the magnetic field evolution of the superconducting state in a
strongly disordered NbN thin film which exhibits a magnetic field tuned
superconductor to insulator-like transition, employing low temperature scanning
tunneling spectroscopy (STS). Transport measurements of the sample reveals a
characteristic magnetic field, which separates the low field state where
resistance decreases with decreasing temperature, i.e. dR/dT > 0 and a
high-field state where dR/dT < 0. However, STS imaging of the superconducting
state reveals a smooth evolution across this field and the presence of a robust
pseudogap on both sides of this characteristic field. Our results suggest that
the superconductor-insulator transition might be a percolative transition
driven by the shrinking of superconducting fraction with magnetic field.
