Published 1992Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: Visible and near infrared cathodoluminescence of Bi2Sr2CaCu2Ox and YBa2Cu3O7−x films is investigated in the scanning electron microscope. In particular, possible analogies in the cathodoluminescence of both systems have been analyzed. The spectra show only minor and slightly defined common features. Low-temperature observations show the capability of the cathodoluminescence technique to detect fine structural transitions. Some transformations induced by the electron beam are described.Type of Medium: Electronic ResourceURL: -

Published 2001Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: We report on the magnetic and superconducting properties of La0.7Ca0.3MnO3/YBa2Cu3O7 (LCMO/YBCO) superlattices. For a constant LCMO layer thickness of 6 unit cells (u.c.), resistance and susceptibility measurements show superconductivity for YBCO layer thickness in excess of 4 unit cells. The critical temperature increases with YBCO thickness, and a Tc of 58 K is found for a YBCO thickness of 10 unit cells. Magnetization measurements show a ferromagnetic transition at 100 K in a (LCMO6 u.c./YBCO5 u.c.)15 bilayer superlattice, and a depressed value of the saturation magnetization of 20 emu cm−3. These results are discussed in terms of interface disorder (analyzed by x-ray diffraction and transmission electron microscopy) and of the possible interaction between magnetism and superconductivity. © 2001 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1998Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: We performed a detailed study of the structure and transport properties of Bi2212/22Y2/2212 planar-type tunnel junctions. Both high-temperature superconducting electrodes and semiconducting barriers are highly epitaxial thin films deposited onto SrTiO3 single-crystal (001) substrates. Deposition of the films was carried out by a high oxygen pressure dc-sputtering technique, which produces high-quality epitaxial thin films, as determined by x-ray diffraction, lattice resolution transmission electron microscopy, and Rutherford backscattering. Critical temperatures for the superconducting electrodes of 85 K were determined by transport measurements (ρ and χ versus T). A study of resistivity as a function of temperature of the semiconducting barriers was performed. Clear quasiparticle tunneling indicating a gap structure at about 30–35 mV, a zero-bias peak, as well as linear and flat background at high voltages have been observed. For junctions with very thin barriers weak-link-type behavior was observed. An analysis of the I–V curves for these junctions has been made based on the resistively shunted junction model. © 1998 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1998Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: The dynamics of magnetization reversal at surfaces and interfaces is studied by a specific photoelectric effect experiment with pulsed soft x rays. This novel time-resolved surface magnetometry is based on the measure of the spin polarization of the total photoejected electron yield by means of a Mott scattering experiment and on the acquisition synchronism with the multibunch structure of the positron storage ring SuperAco at Orsay (500 ps pulses at 120 ns intervals). We present results on the fast magnetization reversal of Fe ultrathin films deposited on amorphous low-coercivity ferromagnetic ribbons. © 1998 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1989Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: We report a study of the dependence of the density of states in hydrogenated amorphous silicon produced under different dc substrate biases. A dependence of the density of states in materials deposited simultaneously onto indium-tin-oxide-coated glass and stainless steel has been found. The same is attributed to sheath plasma differences at the top surface of the growing film. The density of states was determined by the space-charge-limited current method. The universal scaling law is tested for samples having a similar density of states. Attempts were made to correlate the product of the hole mobility and the recombination time for samples deposited in conditions similar to those used in the space-charge-limited current experiments.Type of Medium: Electronic ResourceURL: -

Published 1996Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: Silicon–carbon–nitrogen alloys have been deposited by electron cyclotron resonance plasma chemical vapor deposition. Nitrogen, methane, and argon diluted silane have been used as precursor gases. The properties of the deposited films were studied by spectroscopic ellipsometry, Fourier transform infrared spectroscopy, X-ray photoelectron, and Auger electron spectroscopy. The structure and bond formation in the SiCN films is discussed in terms of the present results. © 1996 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1996Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: We have deposited Bi2Sr2CaCu2O8+δ/Bi2Sr2YCu2O8+δ/Bi2Sr2CaCu2 O+δ (2212/22Y2/2212) heterostructures by an in situ dc sputtering technique at high oxygen pressures on (001) SrTiO3 substrates. The formation of highly c-axis oriented trilayers with sharp interfaces is demonstrated by x-ray diffraction and transmission electron microscope (TEM) analysis. Both the top and the bottom 2212 layers are superconducting below 87 K. Tunneling phenomena on junctions fabricated from these trilayers are observed. The conductance versus voltage curves at low temperatures exhibit a change of slope indicative of a gap structure at about 30 mV, a zero-bias peak, as well as linear background at high voltages. © 1996 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1996Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: Carbon nitride thin films obtained by dual ion beam sputtering have been investigated by electron energy-loss spectroscopy (EELS), transmission electron microscopy, and Fourier transform infrared spectroscopy. The nitrogen content in the films depends on deposition conditions. A maximum value of N/C=0.8 has been achieved. A new peak at 286.7 eV energy loss in the C K-edge EELS spectra has been assigned to C=N bonds with C in the sp2 hybridization state. In addition, experimental evidences are presented of the formation of β-C3N4 crystallites embedded in a layer of a polymer like CNx amorphous phase. An evaluation of the experimental parameters that lead to the highest N content in the films is also included. © 1996 American Institute of Physics.Type of Medium: Electronic ResourceURL: -
