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.

Epitaxial Relationship

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.

AbstractIn this study we report on in-situ growth of lead zirconate titanate (PbZr1-xTixO3, PZT) and strontium titanate (SrTiO3, STO) films by pulsed laser deposition at 248 nm. Films were deposited in an oxygen background at elevated temperatures on a variety of substrates including MgO(l00), Pt(100)/MgO(100), Pt(111)/MgO(111), Pt(110)/MgO(110), Pt(111)/SiO2/Si, and Pt(111)/glass.Deposited films were characterized by Rutherford Backscattering Spectroscopy (RBS), x-ray diffraction (XRD), and electrical (dielectric constant and leakage) measurements. A strong substrate dependence was found for both the fraction of pyrochlore (Pb2Zr2-xTixO7) phase in the PZT films, and the STO film dielectric constants. The origin of the substrate dependence is discussed with regard to nucleation and interface layer cffects, and the chemistry of the relevant materials.
