Title Development of the experimental setup for investigation of latching of superconducting single-photon detector caused by blinding attack on the quantum key distribution system Type Conference Article
Year 2017 Publication EPJ Web Conf. Abbreviated Journal EPJ Web Conf.
Volume 132 Issue Pages 01004 (1 to 2)
Keywords QKD, SSPD, SNSPD
Abstract Recently bright-light control of the SSPD has been demonstrated. This attack employed a “backdoor” in the detector biasing scheme. Under bright-light illumination, SSPD becomes resistive and remains “latched” in the resistive state even when the light is switched off. While the SSPD is latched, Eve can simulate SSPD single-photon response by sending strong light pulses, thus deceiving Bob. We developed the experimental setup for investigation of a dependence on latching threshold of SSPD on optical pulse length and peak power. By knowing latching threshold it is possible to understand essential requirements for development countermeasures against blinding attack on quantum key distribution system with SSPDs.

Title High resolution THz gas spectrometer based on semiconductor and superconductor devices Type Conference Article
Year 2017 Publication EPJ Web Conf. Abbreviated Journal EPJ Web Conf.
Volume 132 Issue Pages 02001 (1 to 2)
Keywords NbN HEB mixers, detectors, THz spectroscopy
Abstract The high resolution THz gas spectrometer consists of a synthesizer based on Gunn generator with a semiconductor superlattice frequency multiplier as a radiation source, and an NbN hot electron bolometer in a direct detection mode as a THz radiation receiver was presented. The possibility of application of a quantum cascade laser as a local oscillator for a heterodyne receiver which is based on an NbN hot electron bolometer mixer is shown. The ways for further developing of the THz spectroscopy were outlined.

Title Submillimeter spectroscopy of semiconductors Type Journal Article
Year 1973 Publication Sov. Phys. JETP Abbreviated Journal Sov. Phys. JETP
Volume 37 Issue 2 Pages 299-304
Keywords semiconductors, submillimeter spectroscopy, spectrometer, BWO, Ge, free excitons
Abstract The possibility is considered of carrying out submillimeter-wave spectral investigations of semiconductors by means of a high resolution spectrometer with backward-wave tubes. Results of a study of the excitation spectra of small impurities, D-(A +) centers and free excitons in germanium are presented.

Title Cyclotron resonance of electrons in Ge in a quantizing magnetic field in the case of inelastic scattering by acoustic phonons Type Journal Article
Year 1975 Publication Sov. Phys. JETP Abbreviated Journal Sov. Phys. JETP
Volume 40 Issue 2 Pages 311-315
Keywords Ge, cyclotron resonance
Abstract Results are presented of an experimental study of the linewidth of cyclotron resonance under strong quantization conditions on the scattering of electrons by acoustic phonons. The measurements were performed in the 2....{).4 mm wavelength range at temperatures between 10 and 1.4 OK. A number of singularities were observed in the temperature and frequency dependences of the cyclotron linewidth. These can be ascribed to the effect of inhomogeneous broadening due to nonparabolicity of the electron spectrum, which is renormalized as a result of interaction with acoustic phonons.

Title Investigation of free excitons in Ge and their condensation at submillimeter wavelengths Type Journal Article
Year 1976 Publication Sov. Phys. JETP Abbreviated Journal Sov. Phys. JETP
Volume 43 Issue 1 Pages 116-122
Keywords Ge, free excitons
Abstract Results are presented of an investigation of free excitons in Ge in the submillimeter wavelength range for low as well as for high excitation levels when interaction between the excitons becomes important. The free-exciton energy spectrum is discussed. It is shown that the drop radii and their concentrations can be determined by measuring the temperature dependence of the free-exciton concentration. A section of the phase diagram is obtained in the 0.5-2.8 K temperature range for the free excitons+condensate system.
