Abstract: The TiO2 films were prepared on Pt/Ti/SiO2/Si substrate by a laser chemical vapor deposition method. With increasing laser power (P L) from 48 to 98W, the deposition temperature (T dep) monotonously increased from 849 to 929K. At T dep=849K (P L=48W), the rutile TiO2 film was prepared with strong (110) and (200) peaks. With increasing T dep from 849 to 883K (P L=71W), the intensity of (110) peak increased. The (110)-oriented TiO2 films were obtained for T dep beyond 903K (P L=81W). All TiO2 films showed faceted grains with the columnar cross-section. With increasing T dep, the grain size increased and the column became wider. The high deposition rate (R dep) ranged from 13.04 to 24.84μmh−1. [Copyright &y& Elsevier]

Abstract: Preferentially oriented thick and thin compacts of zeolite L with a large anisotropy in their crystal structures were successfully prepared by colloidal processes in a strong 12T magnetic field. The orientation along the direction of the applied magnetic field was characterized by XRD using slip-cast compacts. In the present experiments, it was revealed that the c-axis of zeolite L was an easy-magnetization axis. The c-axis oriented zeolite L layer with a thickness of ca. 3μm was formed on a porous ceramics substrate via electrophoretic deposition in a strong magnetic field applied perpendicular to the surface of the substrate.

Abstract: A series of lanthanum and calcium modified PbTiO3 [(Pb1−x−y La x Ca y )Ti1−x/4O3] thin films deposited on (111)Pt/Ti/SiO2/Si substrate were successfully achieved using a sol–gel route. It was found that all the (Pb1−x−y La x Ca y )Ti1−x/4O3 films exhibited high (100)-orientation, and the La and Ca contents played a significant role in their electric properties. The dielectric loss, fatigue and leakage current characteristics of films became worse with increasing Ca content, and the (Pb1−x−y La x Ca y )Ti1−x/4O3 film (x=0.1,y=0.1) possessed excellent piezoelectric and ferroelectric properties with maximum piezoelectric constant (d 33∼132pm/v) and maximum remanent polarization (Pr∼29μC/cm2). These results indicate that the highly oriented (Pb1−x−y La x Ca y )Ti1−x/4O3 film with appropriate content of La and Ca doped is a promising candidate for the mechatronics and MEMS applications.
