HREM lattice images have been obtained using forbidden reflections generated by (111) stacking faults in silicon lying normal to the beam at temperatures up to 600 °C. Stationary and video images of 30°/90° partial dislocations relaxing toward equ

Certain classes of semiconductor quantum dots being actually fabricated exhibit a nearly parabolic confinement for both the electron and the hole. In undoped quantum dots, excitonic effects are important. In this work, first we present theoretical re

appliqud. Abstract. The coupled motion of the vortex lattices of two electrically insulated, superimposed, superconducting thin films (primary and secondary) in a perpendicular magnetic field, is predicted to exhibit a Josephson-like behavior. For a

The theoretical and experimental behaviour of two magnetic field controlled superconducting structures both patterned in a YBaCuO thin film on MgO substrate are compared. One is based on the flux flow of Abrikosov vortices and the other one on the in

The fundamental aspects of vortices in layered superconductors (natural or artificial multilayered materials) are reviewed, focusing on the role of anisotropy and very short coherence lengths. These materials divide into three classes, with increasin

We determine the magnetic vector potential for a ferromagnetic plate in the steady state conditions with eddy currents which are induced by sliding field currents. Our plate has non linear magnetic B(H) characteristic. We deduce the cyclic impedance
