  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 (up) 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
  Year 1984 Publication Физика и техника полупроводников Abbreviated Journal Физика и техника полупроводников  
  Volume 18 Issue (up) 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.

  Keywords submillimeter radio telescope  
  Abstract В статье исследуется возможность использования сверхпроводящего материала в качестве отражающего слоя зеркала субмиллиметрового телескопа, охлажденного до криогенных температур и предназначенного для наблюдений реликтового излучения.

  Title Individual SWCNT transistor with photosensitive planar junction induced by two‐photon oxidation Type Journal Article
  Year 2021 Publication Adv. Electron. Mater. Abbreviated Journal Adv. Electron. Mater.  
  Volume 7 Issue (up) 3 Pages 2000872  
  Keywords SWCNT transistors  
  Abstract The fabrication of planar junctions in carbon nanomaterials is a promising way to increase the optical sensitivity of optoelectronic nanometer-scale devices in photonic connections, sensors, and photovoltaics. Utilizing a unique lithography approach based on direct femtosecond laser processing, a fast and easy technique for modification of single-walled carbon nanotube (SWCNT) optoelectronic properties through localized two-photon oxidation is developed. It results in a novel approach of quasimetallic to semiconducting nanotube conversion so that metal/semiconductor planar junction is formed via local laser patterning. The fabricated planar junction in the field-effect transistors based on individual SWCNT drastically increases the photoresponse of such devices. The broadband photoresponsivity of the two-photon oxidized structures reaches the value of 2 × 107 A W−1 per single SWCNT at 1 V bias voltage. The SWCNT-based transistors with induced metal/semiconductor planar junction can be applied to detect extremely small light intensities with high spatial resolution in photovoltaics, integrated circuits, and telecommunication applications.

  Title Possibilities of acoustic thermometry for controlling targeted drug delivery Type Journal Article
  Year 2015 Publication Acoust. Phys. Abbreviated Journal  
  Volume 61 Issue (up) 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 (up) 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 Проявление внутримолекулярных вибронных взаимодействий в тонкоструктурных спектрах флуоресценции и возбуждения флуоресценции полиеновых δ-диметиламинокетонов Type Journal Article
  Year 2011 Publication Оптический журнал Abbreviated Journal Опт. ж.  
  Volume 78 Issue (up) 5 Pages 3-8  
  Keywords спектры флуоресценции; вибрационный анализ; адиабатическое гармоническое приближение; бесфононная линия; фононное крыло  
  Abstract Проведен вибрационный анализ спектров флуоресценции и возбуждения флуоресценции, полученных методом Шпольского при 4,2 K. Рассчитаны параметры внутримолекулярных взаимодействий двух δ-диметиламинокетонов. Для определения интегральных интенсивностей вибронных полос в спектрах с тонкой структурой на интенсивном сплошном фоне выполнено моделирование спектров путем представления полосы каждого из вибронных переходов бесфононной линией и фононным крылом с определенными параметрами (полуширинами, фактором Дебая–Валлера). Показано, что нарушение зеркальной симметрии в сопряженных спектрах флуоресценции и возбуждения флуоресценции этих двух соединений может быть обÑŠяснено интерференцией франк-кондоновского и герцберг-теллеровского взаимодействий.
