| Title |
Intense electromagnetic radiation heating of superconductor electrons in resistive state | Type | Journal Article | ||
| Year | 1988 | Publication | Fizika Nizkikh Temperatur | Abbreviated Journal | Fizika Nizkikh Temperatur |
| Volume | 14 | Issue | 7 | Pages | 753-763 |
| Keywords | Nb HEB | ||||
| Abstract | An experimental study is made of the effect of intense radiation in the millimeter and submillimeter ranges on thin and narrow Nb films in the resistive state. It is found that the excess resistance resulting from radiation and the dependence of its relaxation time on radiation intensity and transport current can be explained in terms of the effect of electron heating. Quantitative agreement is obtained between the experimental data and a homogeneous electron heating model. | ||||

Interaction of electrons with thermal phonons in YBa2Cu3O7-δ films at low temperatures | Type | Journal Article | ||
| Year | 1989 | Publication | JETP Lett. | Abbreviated Journal | JETP Lett. |
| Volume | 50 | Issue | 5 | Pages | 283-286 |
| Keywords | YBCO HTS films | ||||
| Abstract | The time of electron-phonon interaction tau(eph) in YBaCuO films at low temperatures is studied. This is measured as the time of resistance relaxation in the resistive state of the superconducter, and is also determined from the increase in resistance under the action of radiation. Consistent results of these methods show that resistance relaxation in the resistive state is caused by cooling of the electron subsystem with respect to the phonon subsystem. The time tau(eph) is found to be inversely proportional to the temperature and comes to 80 ps when T = 1.6 K and 5 ps when T = 30 K. 6 refs. | ||||

| Title |
Interrelation of resistivity and inelastic electron-phonon scattering rate in impure NbC films | Type | Journal Article | ||
| Year | 1998 | Publication | Phys. Rev. B | Abbreviated Journal | Phys. Rev. B |
| Volume | 57 | Issue | 24 | Pages | 15623-15628 |
| Keywords | NbC films | ||||
| Abstract | A complex study of the electron-phonon interaction in thin NbC films with electron mean free path l=2–13nm gives strong evidence that electron scattering is significantly modified due to the interference between electron-phonon and elastic electron scattering from impurities. The interference T2 term, which is proportional to the residual resistivity, dominates over the Bloch-Grüneisen contribution to resistivity at low temperatures up to 60 K. The electron energy relaxation rate is directly measured via the relaxation of hot electrons heated by modulated electromagnetic radiation. In the temperature range 1.5–10 K the relaxation rate shows a weak dependence on the electron mean free path and strong temperature dependence ∼Tn, with the exponent n=2.5–3. This behavior is explained well by the theory of the electron-phonon-impurity interference taking into account the electron coupling with transverse phonons determined from the resistivity data. | ||||

| Abstract | THE 25th International Symposium on Space Terahertz Technology (ISSTT) was held in Moscow, Russia, between April 27–30, 2014. The conference was organized by Moscow State Pedagogical University and the Higher School of Economics (National Research University) and Chaired by Professor Gregory Gol'tsman of Moscow State Pedagogical University. The conference was attended by roughly 150 participants from 15 countries. The technology covered by ISSTT includes detectors, devices, circuits and systems in various areas of THz science and technology. Each year this symposium brings together the global THz space science technology community, and as such, emphasizes the broad international collaboration that is required to execute these large complicated instrument programs that dominate this field. However, talks covering technologies for balloon, aircraft, and ground-based telescopes were also presented. In this special section of IEEE Transactions on Terahertz Science and Technology, we include eight expanded papers from the 25th ISSTT symposium. The papers range from development of SIS mixers to optical adjustment systems for radio telescopes. The 26th ISSTT will be held in Boston, MA, USA, during March 16–18, 2015. Researchers and scientist involved in THz research are invited to attend this symposium (more details are at http://www.cfa.harvard.edu/events/2015/isstt2015/). You can access the full list of papers presented at the ISSTT symposia from the National Radio Astronomy Observatory website: http://www.nrao.edu/meetings/isstt/index.shtml Yours sincerely |

Investigating the detection regimes of a superconducting single-photon detector | Type | Journal Article | ||

| Volume | 80 | Issue | 7 | Pages | 435 |

| Abstract | The detection regimes of a superconducting single-photon detector have been investigated. A technique is proposed for determining the regions in which “pure regimes” predominate. Based on experimental data, the dependences of the internal quantum efficiency on the bias current are determined in the one-, two-, and three-photon detection regimes. | ||||

Investigation of a superconducting hot electron mixer | Type | Conference Article | ||

| Keywords | HEB mixers | ||||
| Abstract | Mixing at 20 GHz in niobium superconducting thin film strips in the resistive state is studied. Experiments give evidence that electron-heating is the main cause of the non linear phenomena. The requirements on the mode of operation and on the film parameters for small conversion loss and the possibility of conversion gain are discussed. Measurements indicate a minimum intrinsic conversion loss around 1 dB with a sharp drop for the lowest voltage bias-points, and a DSB mixer noise temperature between 100 and 450 K at 20 GHz. The device output noise temperature at the mixer operating point can be as low as 30-50 K. A simple theory is presented, which is based on the assumption that the small signal resistance is linearly dependent on power. This type of mixer is considered very promising for use in low-noise heterodyne receivers at THz frequencies. | ||||

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. | ||||
