AbstractThe growth, structural and cathodoluminescent (CL) properties of europium activated yttrium oxide (Eu:Y2O3) thin films are reported. The Eu:Y2O3 films were grown in-situ using a pulsed laser deposition technique. Our results show that Eu:Y2O3 films can grow epitaxially on (100) LaAlO3 substrates under optimized deposition parameters. The epitaxial growth of Eu:Y2O3 films on LaAlO3, which has a lattice mismatch of ∼ 60 %, is explained by matching of the atom positions in the lattices of the film and the substrate after a rotation. CL data from these films are consistent with highly crystalline Eu:Y2O3 films with an intense CL emission at 611 nm.

AbstractBa0.5Sr0.5TiO3 (BSTO) thin films were grown on (001) MgO using pulsed-laser deposition (PLD). The microstructures of in-situ and ex-situ annealed BSTO films were studied by X-ray diffraction and transmission electron microscopy (TEM). The films showed a cube on cube epitaxial relationship with <100> BSTO // <100> MgO. They were essentially single crystals with a columnar structure and possessed smooth surfaces. The interfaces of the BSTO films and substrates were atomically sharp, with misfit dislocations. Better crystallinity and full strain relaxation was obtained in films grown in 10-1 mbar oxygen and annealed ex-situ. A 30% increase in dielectric tuneability was achieved compared with in-situ annealing and deposition at 10-4 mbar. Threading dislocations are the dominant defects in the films grown in 10-1 mbar oxygen and annealed ex-situ, while the films with in-situ annealing show columnar structures with low angle boundaries.

ABSTRACTThe influence of an in-situ magnetic field on the plume during pulsed laser deposition (PLD) to prepare epitaxial nickel zinc ferrite (NZF) thin films were investigated. An air core coil (solenoid coil) was installed between a target and a substrate, and up to 43 mT of magnetic field was generated by direct current (DC)(Dynamic Aurora PLD method). Application of magnetic field brought about following structural and property changes;(1) deposition rate was almost doubled, (2) the concentration of Ni and Zn in the film was decreased, (3) lattice parameter was unchanged, and (4) magnetization and coercivity was increased. Since deposition rate was increased by application of magnetic field, films with same thickness was also prepared without magnetic field, however, magnetic properties were unchanged. This indicates that application of in-situ magnetic field improved magnetic properties.
