Notizen:
Epitaxial BaRuO3 (BRO) and CaRuO3 (CRO) thin films were prepared on (001), (110) and(111) SrTiO3 (STO) single-crystal substrates by laser ablation, and their microstructures andanisotropy of electrical conductivity were investigated. The (205) (104), (110) and (009) orientedBRO thin films, and (001), (110) and (110) oriented CRO thin films were grown epitaxially on (001),(110) and (111) STO substrates with in-plain orientation, respectively. The (009) BRO thin film and(001) CRO thin film has a flat surface result from a good lattice matching to STO substrates. The(205) (104) BRO thin film and (111) CRO thin film exhibited orthogonal- and hexagonal-shapedtexture, respectively. The (110) BRO thin film and (110) CRO thin film showed an island growth dueto (110) surface feature of cubic perovskite structure. Epitaxial BRO and CRO thin films have a highelectrical conductivity with a metallic conduction, the (111) CRO thin films exhibited the highestconductivity of 1.4×105 S·m-1
