Bismuth-based layer-structured Bi5Fe0.5Co0.5Ti3O15(BFCT) thin films have been deposited on Pt/Ti/SiO2/Si substrates by chemical solution deposition method. Using different heating rates during crystallization, we obtained randomly oriented and highlyc-axis-oriented BFCT films. Anisotropic ferroelectricity were determined with the remnant polarization (2Pr) ∼ 45.8μC/cm2for randomly oriented film and 2Pr∼ 25.3μC/cm2for highlyc-axis-oriented ones. Meanwhile, highlyc-axis-oriented BFCT film shows better fatigue endurance than that of random orientation. Both above can confirm the ferroelectric anisotropy. Furthermore, magnetic anisotropy also has been observed and possible reasons were discussed. [ABSTRACT FROM AUTHOR]

Highly oriented titanate nanotube (TNT) film was successfully synthesized by a simple electrophoretic deposition (EPD) method without any hard templates and surfactants. This oriented films adequately utilized the excellent properties of ID nanomaterials such as single crystal semiconductor architectures, large surface area, and superior charge transport, which lead to higher photocatalytic activity. We believe that this versatile method can be extent to fabricate other ordered ID nanomaterials films. [ABSTRACT FROM AUTHOR]

A series of PZT based ferroelectric thin films obtained by multitarget sputtering with different preferential orientations are studied by piezoresponse force microscopy (PFM). The modification of the substrate by the deposition of an extra TiO x layer, and the use of MgO-based substrates instead of the usual Si-based ones, change the preferential orientation of the films. The results of the analysis of the local piezoelectric properties allow us to discuss the origin of some special features observed, like the appearance of protruding grains in films with specific orientations, and the homogeneity of the piezoelectric performance at the nanoscale.
