Title An ultra-fast superconducting Nb nanowire single-photon detector for soft x-rays Type Journal Article
Year 2012 Publication Abbreviated Journal Appl. Phys. Lett.
Volume 101 Issue Pages
Keywords SSPD, SNSPD, x-ray, Nb
Abstract Although superconducting nanowire single-photon detectors (SNSPDs) are well studied regarding the

detection of infrared/optical photons and keV-molecules, no studies on continuous x-ray photon

counting by thick-film detectors have been reported so far. We fabricated a 100 nm thick niobium

x-ray SNSPD (an X-SNSPD) and studied its detection capability of photons with keV-energies in

continuous mode. The detector is capable to detect photons even at reduced bias currents of 0.4%,

which is in sharp contrast to optical thin-film SNSPDs. No dark counts were recorded in extended

measurement periods. Strikingly, the signal amplitude distribution depends significantly on the photon

energy spectrum.VC

Title The electron-phonon relaxation time in thin superconducting titanium nitride films Type Journal Article
Year 2013 Publication Appl. Phys. Lett. Abbreviated Journal Appl. Phys. Lett.
Volume 103 Issue 25 Pages 252602 (1 to 4)
Keywords disordered TiN films, electron-phonon relaxation time
Abstract We report on the direct measurement of the electron-phonon relaxation time, τeph, in disordered TiN films. Measured values of τeph are from 5.5 ns to 88 ns in the 4.2 to 1.7 K temperature range and consistent with a T−3 temperature dependence. The electronic density of states at the Fermi level N0 is estimated from measured material parameters. The presented results confirm that thin TiN films are promising candidate-materials for ultrasensitive superconducting detectors.

Title Low noise and wide bandwidth of NbN hot-electron bolometer mixers Type Journal Article
Year 2011 Publication Appl. Phys. Lett. Abbreviated Journal Appl. Phys. Lett.
Volume 98 Issue Pages 033507 (1 to 3)
Keywords NbN HEB mixer
Abstract We report a record double sideband noise temperature of 600 K (5hν/kB) offered by a NbN hot-electron bolometer receiver at 2.5 THz. Allowing for standing wave effects, this value was found to be constant in the intermediate frequency range 1–7 GHz, which indicates that the mixer has an unprecedentedly large noise bandwidth in excess of 7 GHz. The insight into this is provided by gain bandwidth measurements performed at the superconducting transition. They show that the dependence of the bandwidth on the mixer length follows the model for an HEB mixer with diffusion and phonon cooling of the hot electrons.
