  Title Influence of the interference of electron-phonon and electron-impurity scattering on the conductivity of unordered Nb films Type Journal Article
  Year 1995 Publication JETP Abbreviated Journal JETP  
  Volume (down) 80 Issue 5 Pages 960-964  
  Keywords  
  Abstract The temperature dependence of the resistivity of Nb thin films has been studied at T=4.2-300 K. It has been shown that quantum interference between electron-phonon and electron-impurity scattering determines the temperature dependence of the resistivity of the films investigated over a broad temperature range. The magnitude of the contribution of the electron-phonon-impurity,interference is described satisfactorily by the theory developed by Reizer and Sergeev {Zh. Eksp. Teor. Fiz. 92,2291 (1987) [Sov. Phys. JETP 65, 1291 (1987)l). The interaction constants of electrons with longitudinal and transverse phonons in Nb films have been determined for the first time by comparing the experimental data with the theory. The values of the constants obtained are consistent with the data on the inelastic electron-phonon scattering times in the films investigated. The contribution of the transverse phonons is dominant both in the interference correction to the resistivity and in the electron energy relaxation.

  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 (down) 78 Issue 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.

  Title Magnetic field effects on the nonohmic impurity conduction of uncompensated crystalline silicon Type Journal Article
  Year 2001 Publication Jetp Lett. Abbreviated Journal Jetp Lett.  
  Volume (down) 73 Issue 1 Pages 44-47  
  Keywords uncompensated crystalline silicon, nonohmic impurity conduction, magnetic field  
  Abstract The impurity conduction of a series of crystalline silicon samples with the concentration of major impurity N ≈ 3 × 1016 cm−3 and with a varied, but very small, compensation K was measured as a function of the electric field E in various magnetic fields H-σ(H, E). It was found that, at K < 10−3 and in moderate E, where these samples are characterized by a negative nonohmicity (dσ(0, E)/dE < 0), the ratio σ(H, E)/σ(0, E) > 1 (negative magnetoresistance). With increasing E, these inequalities are simultaneously reversed (positive nonohmicity and positive magnetoresistance). It is suggested that both negative and positive nonohmicities are due to electron transitions in electric fields from impurity ground states to states in the Mott-Hubbard gap.

  Title Amplification of a Raman scattering signal by carbon nanotubes Type Journal Article
  Year 2018 Publication Dokl. Phys. Abbreviated Journal Dokl. Phys.  
  Volume (down) 63 Issue 12 Pages 496-498  
  Keywords carbon nanotubes, CNT, Raman scattering, RLS  
  Abstract The effect of Raman scattering (RLS) signal amplification by carbon nanotubes (CNTs) was studied. Single-layered nanotubes were synthesized by the chemical vapor deposition (CVD) method using methane as a carbon-containing gas. The object of study used was water, the Raman spectrum of which is rather well known. Amplification of the Raman scattering signal by several hundred percent was attained in our work. The maximum amplification of a Raman scattering signal was shown to be achieved at an optimal density of nanotubes on a substrate. This effect was due to the scattering and screening of plasmons excited in CNTs by neighboring nanotubes. The amplification mechanism and the possibilities of optimization for this effect were discussed on the basis of the theory of plasmon resonance in carbon nanotubes.

  Title Superconducting microstructures with high impedance Type Journal Article
  Year 2020 Publication Phys. Solid State Abbreviated Journal Phys. Solid State  
  Volume (down) 62 Issue 9 Pages 1539-1542  
  Keywords superconducting channels, SIS, inetic inductance, tunneling contacts, high impedance  
  Abstract The transport properties of two types of quasi-one-dimensional superconducting microstructures were investigated at ultra-low temperatures: the narrow channels close-packed in the shape of meander, and the chains of tunneling contacts “superconductor-insulator-superconductor.” Both types of the microstructures demonstrated high value of high-frequency impedance and-or the dynamic resistance. The study opens up potential for using of such structures as current stabilizing elements with zero dissipation.

  Title Electron-phonon interaction in disordered conductors: Static and vibrating scattering potentials Type Journal Article
  Year 2000 Publication Phys. Rev. B. Abbreviated Journal Phys. Rev. B.  
  Volume (down) 61 Issue 9 Pages 6041-6047  
  Keywords disordered conductors, scattering potential, electron-phonon interaction  
  Abstract Employing the Keldysh diagram technique, we calculate the electron-phonon energy relaxation rate in a conductor with the vibrating and static δ-correlated random electron-scattering potentials. If the scattering potential is completely dragged by phonons, this model yields the Schmid’s result for the inelastic electron-scattering rate τ−1e−ph. At low temperatures the effective interaction decreases due to disorder, and τ−1e−ph∝T4l (l is the electron mean-free path). In the presense of the static potential, quantum interference of numerous scattering processes drastically changes the effective electron-phonon interaction. In particular, at low temperatures the interaction increases, and τ−1e−ph∝T2/l. Along with an enhancement of the interaction, which is observed in disordered metallic films and semiconducting structures at low temperatures, the suggested model allows us to explain the strong sensitivity of the electron relaxation rate to the microscopic quality of a particular film.

  Title Possibilities of acoustic thermometry for controlling targeted drug delivery Type Journal Article
  Year 2015 Publication Acoust. Phys. Abbreviated Journal  
  Volume (down) 61 Issue 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.
