Improving the Spectral Bandwidth of Superconducting Nanowire Single-Photon Detectors (SNSPDs) Karlsruher Schriftenreihe zur Supraleitung Bd20 - Ilya Charaev Kartoniert (TB)

This work presents a comprehensive investigation of the influence of geometry-dependent factors on performance metrics of superconducting single-photon detectors. With fundamental knowledge main investigations are focused to extend the spectral bandwidth and to enhance the detection efficiency especially in infrared range. The developed technology of single-spiral detectors and unconventional electron-beam lithography allows to improve the performance of superconducting detectors.
