This review discusses recent advances in understanding origins of large piezoelectric properties in some ferroelectric materials. In particular, it addresses the role of polarization rotation and monoclinic phases. It is suggested that the polarization rot ...
The integration of ferroelectrics in electronic devices requires that they be used in the form of thin films, which implies that for such systems finite-size effects related to the presence of a ferroelectric-electrode interface become important. In this t ...
Ferroelectrics are characterised by a spontaneous polarisation that can be reversed by an external electric field. The stability of the polarisation states and the possibility for controlled switching between the states render ferroelectric materials very ...
In this paper we report the fabrication and detailed electrical characterization of a Metal-Ferroelectric-Oxide-Semiconductor Capacitor aiming at the extraction of the polarization characteristic. In order to evaluate the electrical performances of the fer ...

Radio frequency (RF) filters based on bulk acoustic wave resonances in piezoelectric thin films have become indispensable components in mobile communications. The currently used material, AlN, exhibits many excellent properties for this purpose. However, i ...
The production of lead zirconate titanate (PZT) with a variation in Zr and Ti ratios using a hydrothermal method has been attempted. We show that when reactions are conducted at 160 degrees C, for 4 h, the phase of PZT produced is independent of the initia ...
The persistent field effect control of ferromagnetism in a diluted magnetic semiconductor by low-voltage polarizing pulses is demonstrated in a ferroelectric gate field effect transistor configuration. The Curie temperature of the (Ga,Mn)As channel is unam ...
We report a 2-step approach to prepare tetragonal perovskite PbZr0.1Ti0.9O3 submicro/nano wires in gram scale and with over 95% wire content. Non-perovskite precursor wires were first fabricated by hydrothermal processing. A subsequent annealing in a PbO a ...
Piezoelectric responses of barium titanate single crystals are investigated along the [720] and [111] directions, respectively, in order to verify the ultrahigh piezoelectric constant (2000 pC/N) reported in a previous study [Appl. Phys. Lett. 86, 012905 ( ...
We present piezoresponse force microscopy measurements on individual integrated potassium niobate (KNbO3) nanowires. The devices consist of KNbO3 nanowires on SiO2 substrates being mechanically clamped and electrically biased by lithographically defined me ...
