Low–angle grain boundaries have been analyzed by transmission electron microscopy (TEM) and electron team induced current (EBIC). Diffusion length and interface recombination velocity have been calculated by measuring the area and the variance of t

We propose a description of the vortex dynamics in YBa 2 Cu 3 O 7− δ films from the critical to the normal states. This description supposes that the vortex motion is thermally activated along the twin boundaries of the films. The discontinuity ob

We propose a description of the transition of YBa2Cu3O7-? films from the superconducting to the normal state. The discontinuity observed in the current-voltage curves at the transition is explained by the sudden increase in the dissipated power rate

The SriZrO2-YBa2Cu3O7 heterostructure constitutes a MIS structure with a particular gate. Under irradiation with visible light, the oxide gate is a sufficiently transparent window to allow photoexcitation near the Si-ZrO2 interface. In these conditio

The activation energy of the individual vortices in superconductive YBa 2 Cu 3 O 7− δ epitaxial thin films is proportional to the temperature in the low temperature range. Data from the literature show that this behavior is similar to that of twin
