EFFECTS OF EPITAXIAL STRAIN ON THE GROWTH MECHANISM OF YBa2Cu3O7−x THIN FILMS IN [YBa2Cu3O7−x/PrBa2Cu3O7−x] SUPERLATTICES
We report on the growth mechanism of YBa2Cu3O7−x. Our study is based on the analysis of ultrathin, YBa2Cu3O7−x layers in c-axis oriented YBa2Cu3O7−x / PrBa2Cu3O7 superlattices. We have found that the release of epitaxial strain in very thin YBCO layers triggers a change in the dimensionality of the growth mode. Ultrathin, epitaxially strained, YBCO layers with thickness below 3 unit cells grow ...

چکیده یکی از مهمترین دغدغه های بزرگ جوامع بشری، از دیر باز تا کنون که ذهن پژوهشگران و متخصصان بهداشت روانی و اجتماعی و دولتها رابه خود مشغول داشته، مسأله ی بزهکاری می باشد. شناخت کامل پدیده ی بزهکاری و بزهکار، علل وعوامل سقوط یک انسان، چگونگی درمان وی و درنهایت پیشگیری ازبزهکاری ودریک کلام سالم سازی یک جامعه، رسالت عظیم، انسانی ومقدسی می باشد که با بررسی شخصیت مجرم یعنی[ انسانی که تحت شرای...
15 صفحه اولAnomalous photovoltaic response in YBa2Cu3O7.
Several experiments were carried out to study the origin of the anomalous photovoltaic eff'ect in high-quality YBa2Cu307 thin films. In particular, the issue of whether the signal is induced by thermal gradients was addressed. Using samples with well-characterized orientation and texture, and using low-power cw lasers, it was determined that the signal was proportional to the thermal gradient a...
متن کاملTwo Crossovers in the Pseudogap Regime of YBa2Cu3O7 Superconductors Observed by Ultrafast Spectroscopy
067002-1 We have investigated the temperature dependence of the optical reflectivity on a femtosecond scale in a near optimally doped YBa2Cu3O7 superconductor. The combined study of the lattice and carrier dynamics at temperatures above Tc allows us to identify two crossover temperatures in the normal state, giving evidence for an inhomogeneity of the pseudogap regime. These crossovers exhibit ...
