In this work, we analyze the residual stress, in both as-grown and post-growth annealed silicon ribbon on a sacrificial carbon template, by the simulation of the thermo-mechanical behavior of the cooling ribbon using the Abaqus software, and the meas

Superconducting YBa2Cu3O7−x (YBCO) thin films grown by pulser-laser-assisted deposition were studied by micro-Raman spectroscopy. This technique was used to estimate the epitaxial quality of the films in terms of the presence of c-axis- and a-axis-

It is reported on the passivation of the mirror facets, opened in the air, of ridge waveguide InGaAs/GaAs/AlGaAs single quantum well (λ=980 nm) laser diodes. The passivation concept consists of two steps, namely, oxide removal by irradiation of the

Yba 2 Cu 3 O 7− δ thin films have been deposited by pulsed laser-assisted deposition (PLD) on (001) SrTiO 3 substrates coated by a lattice-matching buffer layer. The buffer layer, deposited by PLD prior to the YBCO film, consisted of a graded La-d

Resume : cet article presente brievement le potentiel de la technique de depot de films minces par ablation d'une cible au moyen d'un faisceau laser puise. Il donne une liste d'utilisations, le plus souvent en laboratoire, de cette technique par l'in

The conductivity σ∗ = σ 1 + j σ 2 of YBCO films grown by pulsed laser assisted deposition on (100) MgO and (1 1 02) Al2O3 substrates was measured at 22 GHz using a microwave transmission method. A peak close to the transition temperature was obs

YBCO thin films grown by PLD (Pulsed Laser Deposition) are studied by microRaman spectroscopy. The results reveal a high degree of structural inhomogeneity, that is analyzed in terms of different causes: stoichiometry failures, both oxygen and cation

Pulsed laser-assisted deposition (PLD) has recently emerged as a most promising film growth technique, at least for basic research, as this has been best demonstrated for highTc superconducting oxides and YBa2Cu3O7−x in particular. This article bri
