  Title Suppressed critical current in superconducting nanowire single-photon detectors with high fill-factors Type Journal Article
  Year 2009 Publication IEEE Trans. Appl. Supercond. Abbreviated Journal  
  Volume 19 Issue 3 Pages 318-322  
  Keywords SNSPD  
  Abstract In this work we present a new fabrication process that enabled the fabrication of superconducting nanowire single photon detectors SNSPD with fill-factors as high as 88% with gaps between nanowires as small as 12 nm. This fabrication process combined high-resolution electron-beam lithography with photolithography. Although this work was motivated by the potential of increased detection efficiency with higher fill-factor devices, test results showed an unexpected systematic suppression in device critical currents with increasing fill-factor.
