摘要
CaTiO3 thin films were prepared by a 193 nm ArF excimer laser deposition method. Epitaxial CaTiO3 thin films were obtained on SrTiO3 (100) substrate and YBa2Cu3Oy (001) deposited on MgO (100) single-crystal substrate. The grown CaTiO3 thin films orientated to (010) direction and the unit cell of CaTiO3 rotated 45-degrees around the [100] axis of the SrTiO3 substrate. It also happened in CaTiO3/YBa2Cu3Oy/MgO system. The static dielectric constant was 120 at room temperature and reached 175 at lower temperatures.
