  Title Possibilities of acoustic thermometry for controlling targeted drug delivery Type Journal Article
  Year 2015 Publication Acoust. Phys. Abbreviated Journal  
  Volume 61 Issue (down) 4 Pages 488-493  
  Keywords acoustic thermometry, liposome suspension, thermography  
  Abstract Model acoustic thermometry experiments were conducted during heating of an aqueous liposome suspension. Heating was done to achieve the liposome phase transition temperature. At the moment of the phase transition, the thermal acoustic signal achieved a maximum and decreased, despite continued heating. During subsequent cooling of the suspension, when lipids again passed through the phase transition point, the thermal acoustic signal again increased, despite a reduction in temperature. This effect is related to an increase in ultrasound absorption by the liposome suspension at the moment of the lipid phase transition. The result shows that acoustic thermography can be used to control targeted delivery of drugs mixed in thermally sensitive liposomes, the integrity of which is violated during heating to the phase transition temperature.

  Title Timing jitter in NbN superconducting microstrip single-photon detector Type Journal Article
  Year 2020 Publication Phys. Rev. Applied Abbreviated Journal Phys. Rev. Applied  
  Volume 14 Issue (down) 4 Pages 044041 (1 to 8)  
  Keywords NbN SSPD, SNSPD  
  Abstract We experimentally study timing jitter of single-photon detection by NbN superconducting strips with width w ranging from 190 nm to 3μm. We find that timing jitter of both narrow (190 nm) and micron-wide strips is about 40 ps at currents where internal detection efficiency η saturates and it is close to our instrumental jitter. We also calculate intrinsic timing jitter in wide strips using the modified time-dependent Ginzburg-Landau equation coupled with a two-temperature model. We find that with increasing width the intrinsic timing jitter increases and the effect is most considerable at currents where a rapid growth of η changes to saturation. We relate it with complicated vortex and antivortex dynamics, which depends on a photon’s absorption site across the strip and its width. The model also predicts that at current close to depairing current the intrinsic timing jitter of a wide strip could be about ℏ/kBTc (Tc is a critical temperature of superconductor), i.e., the same as for a narrow strip.

  Title High-performance superconducting photon-number-resolving detectors with 86% system efficiency at telecom range Type Journal Article
  Year 2019 Publication J. Opt. Soc. Am. B Abbreviated Journal J. Opt. Soc. Am. B  
  Volume 36 Issue (down) 3 Pages B20  
  Keywords NbN PNR SSPD, SNSPD  
  Abstract The use of improved fabrication technology, highly disordered NbN thin films, and intertwined section topology makes it possible to create high-performance photon-number-resolving superconducting single-photon detectors (PNR SSPDs) that are comparable to conventional single-element SSPDs at the telecom range. The developed four-section PNR SSPD has simultaneously an 86±3% system detection efficiency, 35 cps dark count rate, ∼2 ns dead time, and maximum 90 ps jitter. An investigation of the PNR SSPD’s detection efficiency for multiphoton events shows good uniformity across sections. As a result, such a PNR SSPD is a good candidate for retrieving the photon statistics for light sources and quantum key distribution systems.

  Volume 3 Issue (down) 3 Pages 83-89  
  Keywords  
  Abstract We optimized technology of thin VN films deposition in order to study VN-based superconducting single-photon detectors. Investigation of the main VN film parameters showed that this material has lower resistivity compared to commonly used NbN. Fabricated from obtained films devices showed 100% intrinsic detection efficiency at 900 nm, at the temperature of 1.7 K starting with the bias current of 0.7·I

  Title NbN single-photon detectors with saturated dependence of quantum efficiency Type Journal Article
  Year 2018 Publication Supercond. Sci. Technol. Abbreviated Journal Supercond. Sci. Technol.  
  Volume 31 Issue (down) 3 Pages 035011 (1 to 8)  
  Keywords NbN SSPD, SNSPD  
  Abstract The possibility of creating NbN superconducting single-photon detectors with saturated dependence of quantum efficiency (QE) versus normalized bias current was investigated. It was shown that the saturation increases for the detectors based on finer films with a lower value of Rs300/Rs20. The decreasing of Rs300/Rs20 was related to the increasing influence of quantum corrections to conductivity of superconductors and, in turn, to the decrease of the electron diffusion coefficient. The best samples have a constant value of system QE 94% at Ib/Ic ~ 0.8 and wavelength 1310 nm.

  Title О механизме динамического сужения линии ЭПР доноров фосфора в кремнии Type Journal Article

  Volume 18 Issue (down) 3 Pages 421-425  
  Keywords Si, phosphorus donors, EPR  
  Abstract Температурная зависимость ширины линии ЭПР доноров Р в Si исследована в интервале концентрации ND=2.5⋅1017−9⋅1017см−3 и температур T=1.7−45 K на образцах с различной степенью компенсации основной примеси. Результаты согласуются с моделью обменного сужения линии при учете температурной зависимости обменного интеграла и тем самым исключают предлагавшийся ранее механизм сужения линии вследствие прыжкового движения электронов по примесным центрам.
