摘要：

We have grown biaxially textured La0.5Sr0.5CoO3 (LSCO) thin films on technically important SiO2/Si substrates by pulsed laser deposition, where a biaxially oriented yttria-stabilized zirconia (YSZ) produced by ion-beam-assisted deposition (IBAD) is used as a seed layer to enhance the texture of LSCO on SiO2/Si. The degree of in-plane texturing of LSCO is directly related to the quality of IBAD-YSZ. The smaller the value of full width at half maximum of the IBAD-YSZ (220) diffraction peak, the higher the crystallinity of the LSCO film. The biaxially oriented LSCO film deposited at 700 degrees C on SiO2/Si shows metallic resistivity versus temperature characteristics and has a room-temperature resistivity of around 110 mu Ohm cm.
