Abstract :
In this paper, we report on a systematic investigation of the structure and electrical properties of c-axis oriented Sr1-xLaxCuO2 (SLCO) thin films grown on BaySr1-yTiO3 (BSTO) buffer layers with tunability of the lattice constant from a0=0.3905 nm (y=0, SrTiO3) to a0=0.4000 nm (y=1, BaTiO3), which is favorable to obtain a quantified result of strain effect. We also report on structure and electrical properties improvement of a-axis oriented SLCO thin films on LAO substrates by strain effect control which has been quantificationally studied by c-axis oriented SLCO thin films.
