We report the effects of oxygen content on the transport properties of La0.7Ca0.3MnO3-δ thin films grown epitaxially on LaAlO3 (001) substrates by RF magnetron sputtering. The as-deposited thin films were annealed and treated by oxygen plasma to improve the oxygen content. We observe that the...

The liquid–gas critical points of metals of the first three main groups and those of selected transition metals have been estimated by scaling with the ionization potential and valence. The critical density is shown to be attached to the percolation threshold of the classically accessible...

The parametric motion of one-electron energy levels of disordered systems near the Anderson localization transition is studied. We perform numerical calculations of the distributions of the first (level velocity) and the second (level curvature) derivatives with respect to a change of boundary...

A simple Kronig-Penney model for 1D mesoscopic systems with disordered δ-peak and finite width potentials is used to study numerically the influence of a constant electric field on the conductance fluctuations and probability distribution. The electric field applied to such systems allows us to...
