Abstract

Using a molecular beam epitaxy deposition technique, c-axis La_2-xSr_xCuO_{4+/- (delta} ) ultrathin films have been prepared on (001) SrTiO₃ substrates. Several superconductive properties such as the critical temperature T_c, the penetration depth (lambda) _ab(0), the activation energy for flux flow (Delta) U and the Hall coefficient R_H are reported for the same set of films. As the dopant content is increased, maximum values for T_c and (Delta) U are observed near the optimum doping while R_H decreases continuously.
