  Title Development of A Silicon Membrane-based Multi-pixel Hot Electron Bolometer Receiver Type Conference Article
  Year 2017 Publication IEEE Trans. Appl. Supercond. Abbreviated Journal (up) IEEE Trans. Appl. Supercond.  
  Volume 27 Issue 4 Pages 6  
  Keywords Multi-pixel, HEB, silicon-on-insulator, horn array  
  Abstract We report on the development of a multi-pixel

Hot Electron Bolometer (HEB) receiver fabricated using

silicon membrane technology. The receiver comprises a

2 × 2 array of four HEB mixers, fabricated on a single

chip. The HEB mixer chip is based on a superconducting

NbN thin film deposited on top of the silicon-on-insulator

(SOI) substrate. The thicknesses of the device layer and

handling layer of the SOI substrate are 20 μm and 300 μm

respectively. The thickness of the device layer is chosen

such that it corresponds to a quarter-wave in silicon at

1.35 THz. The HEB mixer is integrated with a bow-tie

antenna structure, in turn designed for coupling to a

circular waveguide,

  Title Introduction to the mini-special-issue on the 25th international symposium on space terahertz technology (ISSTT) Type Miscellaneous
  Year 2015 Publication IEEE Trans. THz Sci. Technol. Abbreviated Journal (up) IEEE Trans. THz Sci. Technol.  
  Volume 5 Issue 1 Pages 14-15  
  Keywords  
  Abstract THE 25th International Symposium on Space Terahertz Technology (ISSTT) was held in Moscow, Russia, between April 27–30, 2014. The conference was organized by Moscow State Pedagogical University and the Higher School of Economics (National Research University) and Chaired by Professor Gregory Gol'tsman of Moscow State Pedagogical University. The conference was attended by roughly 150 participants from 15 countries. The technology covered by ISSTT includes detectors, devices, circuits and systems in various areas of THz science and technology. Each year this symposium brings together the global THz space science technology community, and as such, emphasizes the broad international collaboration that is required to execute these large complicated instrument programs that dominate this field. However, talks covering technologies for balloon, aircraft, and ground-based telescopes were also presented.

In this special section of IEEE Transactions on Terahertz Science and Technology, we include eight expanded papers from the 25th ISSTT symposium. The papers range from development of SIS mixers to optical adjustment systems for radio telescopes. The 26th ISSTT will be held in Boston, MA, USA, during March 16–18, 2015. Researchers and scientist involved in THz research are invited to attend this symposium (more details are at http://www.cfa.harvard.edu/events/2015/isstt2015/).

You can access the full list of papers presented at the ISSTT symposia from the National Radio Astronomy Observatory website: http://www.nrao.edu/meetings/isstt/index.shtml

  Title Comparison of hot-spot formation in NbN and MoN thin superconducting films after photon absorption Type Conference Article
  Year 2017 Publication IEEE Transactions on Applied Superconductivity Abbreviated Journal (up) IEEE Transactions on Applied Superconductiv  
  Volume 27 Issue 4 Pages 5  
  Keywords Thin film devices, Superconducitng photoncounting devices, Nanowire single-photon detectors  
  Abstract In superconducting single-photon detectors SSPD

the efficiency of local suppression of superconductivity and hotspot

formation is controlled by diffusivity and electron-phonon

interaction time. Here we selected a material, 3.6-nm-thick MoNx

film, which features diffusivity close to those of NbN traditionally

used for SSPD fabrication, but with electron-phonon interaction

time an order of magnitude larger. In MoNx detectors we study

the dependence of detection efficiency on bias current, photon

energy, and strip width and compare it with NbN SSPD. We

observe non-linear current-energy dependence in MoNx SSPD

and more pronounced plateaus in dependences of detection

efficiency on bias current which we attribute to longer electronphonon

interaction time.

  Title Effect of the wire geometry and an externally applied magnetic field on the detection efficiency of superconducting nanowire single-photon detectors Type Abstract
  Year 2013 Publication INIS Abbreviated Journal (up) INIS  
  Volume 46 Issue 8 Pages 1-3  
  Keywords TaN, NbN SSPD, SNSPD  
  Abstract The interest in single-photon detectors in the near-infrared wavelength regime for applications, e.g. in quantum cryptography has immensely increased in the last years. Superconducting nanowire single-photon detectors (SNSPD) already show quite reasonable detection efficiencies in the NIR which can even be further improved. Novel theoretical approaches including vortex-assisted photon counting state that the detection efficiency in the long wavelength region can be enhanced by the detector geometry and an applied magnetic field. We present spectral measurements in the wavelength range from 350-2500 nm of the detection efficiency of meander-type TaN and NbN SNSPD with varying nanowire line width from 80 to 250 nm. Due to the used experimental setup we can accurately normalize the measured spectra and are able to extract the intrinsic detection efficiency (IDE) of our detectors. The results clearly indicate an improvement of the IDE depending on the wire width according to the theoretic models. Furthermore we experimentally found that the smallest detectable photon-flux can be increased by applying a small magnetic field to the detectors.

  Title Energy-gap dynamics of a superconductor NbN studied by time-resolved terahertz spectroscopy Type Abstract
  Year 2012 Publication INIS Abbreviated Journal (up) INIS  
  Volume 45 Issue 12 Pages 1-3  
  Keywords NbN energy gap  
  Abstract Using time-resolved terahertz (THz) spectroscopy we performed direct studies of the photoinduced suppression and recovery of the SC gap in a conventional SC NbN. Both processes are found to be strongly temperature and excitation density dependent. The analysis of the data with the established phenomenological Rothwarf-Taylor model enabled us to determine the important microscopic constants: the Cooper pair-breaking rate via phonon absorption and the bare quasiparticle recombination rate. From the latter we were able to extract the dimensionless electron-phonon coupling constant, λ=1.1±0.1, in excellent agreement with theoretical estimates. The technique also allowed us to determine the absorbed energy required to suppress SC, which in NbN equals the thermodynamic condensation energy (in cuprates the two differ by an order of magnitude). Finally, we present the first studies of dynamics following resonant excitation with intense narrow band THz pulses tuned to above and below the superconducting gap. These suggest an additional process, particularly pronounced near Tc, that could be attributed to amplification of SC via effective quasiparticle cooling.
