    Abstract

    We have studied epitaxial strain effect on superconductivity in single-crystal La2-x Srx CuO4 films grown by liquid-phase epitaxy method on (001) La2 CuO4 substrates. Due to lattice mismatch the as-grown films suffer a compressive strain in the c axis and an orthorhombic tensile strain on the ab plane with almost no relaxation up to several micrometers thickness. Our results show that La2-x Srx CuO4 (0.10≤x≤0.15), which is superconducting in the bulk at low temperatures, transforms to an insulating state under such strain.
