Title (up) 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.

Title (up) 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 (up) 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.
