Strain-induced metal-insulator transition in <i>t</i><sub>2g</sub> electron system of perovskite titanate Sm<sub>0.5</sub>Ca<sub>0.5</sub>TiO<sub>3</sub> filmss
Abstract
We have demonstrated a strain-induced metal-insulator transition for weak Jahn-Teller effects in a t 2gelectron system of Sm 0.5 Ca 0.5 TiO 3, which has metallic ground states in the bulk. A clear variation of electronic properties in Sm 0.5 Ca 0.5 TiO 3thin films was investigated as a function of epitaxial stain by changing a substrate and the film thickness. Under strong biaxial tensile strain, metallic behaviors were completely eliminated, as evidenced by the temperature dependence of resistivity. The observed metal-insulator transition was consistent with the behavior of the Ti 3ddensity of states at the Fermi level seen in valence band hard x-ray photoemission spectra.
