Title Photoluminescence and energy‐loss rates in GaAs quantum wells under high‐density excitation Type Journal Article
Year 1987 Publication (up) J. Appl. Phys. Abbreviated Journal
Volume 62 Issue 3 Pages 1010-1016
Keywords 2DEG, GaAs/AlGaAs, heat flow, electron-phonon, hole-phonon, carrier-phonon, interactions
Abstract The time‐resolved luminescence spectra from excited conduction subbands in three samples of multi‐quantum‐well GaAs/AlxGa1-xAs (x=0.3 and 1) semiconductors with several well widths and barrier heights were obtained under high‐density excitations by a 30‐ps pulsed laser at 532 nm, which generated electron–hole pairs to the concentration of 1010–1013/cm2 per well per pulse at 77 K. The temperature and the Fermi energy of electron were determined by fitting best the constructed time‐resolved spectrum to the observed, and the time‐dependent electron energy was obtained by using these parameters. The energy‐loss rates of hot electrons are at least twice smaller than the calculated ones induced by the electron‐polar phonon scattering, including the screening effect due to the high carrier density.

Title Measurement of the energy gap in the compound YBaCu3O9-δ on the basis of the IR absorption spectrum Type Journal Article
Year 1987 Publication (up) JETP Lett. Abbreviated Journal JETP Lett.
Volume 46 Issue 5 Pages 237-238
Keywords YBCO HTS detectors
Abstract For the first time the long-wave infrared absorption spectrum has been measured by means of the bolometric effect and energy gap for high-temperature superconducting ceramics YBa/sub 2/Cu/sub 3/O/sub 9-delta/ has been determined from absorption threshold. 2delta/kT/sub c/ value is equal to 0.6.

Title Light-induced heating of electrons and the time of the inelastic electron-phonon scattering in the YBaCuO compound Type Journal Article
Year 1987 Publication (up) JETP Lett. Abbreviated Journal JETP Lett.
Volume 46 Issue 6 Pages 285-287
Keywords YBCO HTS HEB
Abstract For the first time, measurements have been made on the electron energy relaxation time due to the electron--phonon interaction in films of the YBaCuO superconductor. The results indicate a significant intensification of the electron--phonon interaction in this compound as compared with normal superconducting metals.
