Characterization of MBE-.grown ultrathin films in the La2.SrCuO4±s system
Abstract
Using a molecular beam epitaxy deposition technique, c-Axis La2-SrCuO4±5 ultrathin films have been prepared on (001) SrTiO3 substrates. Several superconductive properties such as the critical temperature T, the penetration depth )tab(O), the activation energy for flux flow zU and the Hall coefficient RH are reported for the same set of films. As the dopant content is increased, maximum values for T and U are observed near the optimum doping while RH decreases continuously.
