摘要：

In the field of high-temperature superconductivity there has been no increase in the critical temperature T-c of bulk compounds since 1993. However, an analysis of the uniaxial strain or pressure derivatives of T-c in the cuprate superconductors allows us to predict that under a compressive epitaxial strain, a large increase of T-c should be possible, We demonstrate the experimental feasibility of this approach for La2-xSrxCuO4+/-delta ("214") thin films deposited on (001)-oriented SrLaAlO4 substrates for different Sr content (0.045 less than or equal to x less than or equal to 0.11). Under epitaxial strain, a large jump of the critical temperature T-c is observed, as well as a drastic change in the resistive behavior from insulating to metallic at low temperatures.
