Ferroelectric materials have attracted interest for over a hundred years as result of their spontaneous polarization and orientation that can be reversed by the application an external electric field. In addition, degree affected stimuli such vibrations, stress, heat, light. These properties enable ferroelectric to used fabricate nanogenerators, which are devices in energy scavenging applicatio...

By means of thin film technology a reduction of size, cost, and power consumption of electronic circuits can be achieved. The required specifications are attained by proper design and combinations of innovative materials and manufacturing technologies. This thesis focuses on the development and fabrication of low-loss ceramic thin film devices for radio and microwave frequency applications. The...

Now that we entered the age of information technology, storage is one of the key issues. Upon scaling down and lowering the operating voltage, FLASH will no longer work. In this paper one of the alternatives is being reviewed; ferroelectric memory devices. Ferroelectrics show non-volatility and can operate at low voltage thresholds. Ferroelectricity shows a P-V hysteresis on which the two level...

One century after the discovery of ferroelectricity, and two decades ferroelectric random access memories were first commercialized, this Special Issue Advanced Electronic Materials demonstrates that field ferroelectricity is in robust health. First, arises very different types material via mechanisms. Second, domains each type are liable to switch differently, for both intrinsic reasons (chemi...

We report the development of a combined machine learning and high-throughput density functional theory (DFT) framework to accelerate search for new ferroelectric materials. The can predict potential compounds using only elemental composition as input. A series machine-learning algorithms initially possible stable insulating stoichiometries with polar crystal structures, necessary ferroelectrici...

To the Editor — The defining property of ferroelectrics is a reversible spontaneous electric polarization whose magnitude and direction can be sensitively tuned by varying temperature, pressure, electric field, strain or chemical composition1. What makes ferroelectrics interesting is the coupling of the electric polarization to other properties of the material. For instance, ferroelectric– ferr...

Hysteretic and nonlinear dielectric behaviour in ferroelectric ceramics has been of interest since 1950s, when these materials found application in various electronic devices. Presently, these phenomena concern with important areas of science, technology and engineering. In particular, nonlinearity and hysteresis are the key factors in performance, precision and accuracy of modern devices. Many...
