  Title Mutual synchronization of two coupled self-oscillators based on GaAs/AlGaAs superlattices Type Journal Article
  Year 2011 Publication Tech. Phys. Abbreviated Journal Tech. Phys.  
  Volume 56 Issue 6 Pages 826-830  
  Keywords (down) GaAs/AlGaAs superlattices  
  Abstract The interaction of self-oscillators based on 30-period weakly coupled GaAs/AlGaAs superlattices is studied. The action of one self-oscillator on the other was observed for a constant bias voltage in the absence of generation of self-sustained oscillations in one of the oscillators. It is shown that induced oscillations in a forced oscillator appear due to excitation of oscillations in the system of coupled oscillators forming the electric-field domain wall at the frequency of one of the higher harmonics of a forcing oscillation.

  Title Terahertz emission from a weakly-coupled GaAs/AlGaAs superlattice biased into three different modes of current self-oscillations Type Journal Article
  Year 2019 Publication AIP Advances Abbreviated Journal AIP Advances  
  Volume 9 Issue 10 Pages 105220  
  Keywords (down) GaAs/AlGaAs superlattice, SL, NbN HEB  
  Abstract Radio-frequency modulated terahertz (THz) emission power from weakly-coupled GaAs/AlGaAs superlattice (SL) has been increased by parallel connection of several SL mesas. Each SL mesa is a self-oscillator with its own oscillation frequency and mode. In coupled non-identical SL mesas biased at different voltages within the hysteresis loop the chaotic, quasiperiodic and frequency-locked modes of self-oscillations of current arise. THz emission was detected when three connected in parallel SL mesas were biased into the frequency-locked and quasiperiodic modes of self-oscillations of current, while in the chaotic mode of those it falls to the noise level.

  Title Tunnel field-effect transistors for sensitive terahertz detection Type Journal Article
  Year 2021 Publication Nat. Commun. Abbreviated Journal Nat. Commun.  
  Volume 12 Issue 1 Pages 543  
  Keywords (down) field-effect transistors, bilayer graphene, BLG  
  Abstract The rectification of electromagnetic waves to direct currents is a crucial process for energy harvesting, beyond-5G wireless communications, ultra-fast science, and observational astronomy. As the radiation frequency is raised to the sub-terahertz (THz) domain, ac-to-dc conversion by conventional electronics becomes challenging and requires alternative rectification protocols. Here, we address this challenge by tunnel field-effect transistors made of bilayer graphene (BLG). Taking advantage of BLG's electrically tunable band structure, we create a lateral tunnel junction and couple it to an antenna exposed to THz radiation. The incoming radiation is then down-converted by the tunnel junction nonlinearity, resulting in high responsivity (>4 kV/W) and low-noise (0.2 pW/[Formula: see text]) detection. We demonstrate how switching from intraband Ohmic to interband tunneling regime can raise detectors' responsivity by few orders of magnitude, in agreement with the developed theory. Our work demonstrates a potential application of tunnel transistors for THz detection and reveals BLG as a promising platform therefor.

  Title Superconductivity behavior in epitaxial TiN films points to surface magnetic disorder Type Journal Article
  Year 2019 Publication Phys. Rev. Applied Abbreviated Journal Phys. Rev. Applied  
  Volume 12 Issue 5 Pages 054001  
  Keywords (down) epitaxial TiN films  
  Abstract We analyze the evolution of the normal and superconducting properties of epitaxial TiN films, characterized by high Ioffe-Regel parameter values, as a function of the film thickness. As the film thickness decreases, we observe an increase of the residual resistivity, that becomes dominated by diffusive surface scattering for d≤20nm. At the same time, a substantial thickness-dependent reduction of the superconducting critical temperature is observed compared to the bulk TiN value. In such high-quality material films, this effect can be explained by a weak magnetic disorder residing in the surface layer with a characteristic magnetic defect density of approximately 1012cm−2. Our results suggest that surface magnetic disorder is generally present in oxidized TiN films.

  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 (down) 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 Electron-phonon interaction in disordered metal films: The resistivity and electron dephasing rate Type Journal Article
  Year 1997 Publication Phys. Rev. B Abbreviated Journal Phys. Rev. B  
  Volume 56 Issue 16 Pages 10089-10096  
  Keywords (down) disordered metal films, electron-phonon interaction, electron dephasing rate, resistivity  
  Abstract The temperature dependence of the resistance of films of Al, Be, and NbC with small values of the electron mean free path l=1.5–10nm has been measured at 4.2–300 K. The resistance of all the films contains a T2 contribution that is proportional to the residual resistance; this contribution has been attributed to the interference between the elastic electron scattering and the electron-phonon scattering. Fitting the data to the theory of the electron-phonon-impurity interference (M. Yu. Reiser and A. V. Sergeev, Zh. Eksp. Teor. Fiz. 92, 224 (1987) [Sov. Phys. JETP 65, 1291 (1987)]), we obtain constants of interaction of the electrons with transverse phonons, and estimate the contribution of this interaction to the electron dephasing rate in thin films of Au, Al, Be, Nb, and NbC. Our estimates are in a good agreement with the experimental data on the inelastic electron-phonon scattering in these films. This indicates that the interaction of electrons with transverse phonons controls the electron-phonon relaxation rate in thin-metal films over a broad temperature range.

  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 61 Issue 9 Pages 6041-6047  
  Keywords (down) 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.

  Volume 263-264 Issue Pages 190-192  
  Keywords (down) disordered conductors, electron-phonon interaction  
  Abstract The electron–phonon interaction is strongly modified in conductors with a small value of the electron mean free path (impure metals, thin films). As a result, the temperature dependencies of both the inelastic electron scattering rate and resistivity differ significantly from those for pure bulk materials. Recent complex measurements have shown that modified dependencies are well described at K by the electron interaction with transverse phonons. At helium temperatures, available data are conflicting, and cannot be described by an universal model.
