Ferroelectricity is a very general phenomenon. Yet it is possible to divide it into three main groups with essentially three different mechanisms: the order-disorder of hydrogen bonds, the trigger effect of nonspherical radicals, and the 4π/3 catastrophe due to high electronic polarizabilities.

Molecule-based ferroelectrics are a class of highly desirable intelligent materials for their rich switchable physical properties, easy and environmentally friendly processing, especial lightweight and mechanical flexibility. In the current work, a new molecule-based ferroelectrics pyridin-4-ylmethanaminium perchlorate was discovered undergoing ...

Piezoelectricity and pyroelectricity, traditionally encountered in certain single crystals and ceramics, have now also been documented in a number of polymers. Recently, one such polymer—poly(vinylidene fluoride)—and some of its copolymers have been shown to be ferroelectric as well.

Ferroelectricity and Ferroelectric Phase Transition
2013Ultrathin crystalline films offer the possibility of exploring phase transitions in the crossover region between two and three dimensions. Second-order ferromagnetic phase transitions have been observed in monolayer magnetic films.

Ferroelectricity in Doped Incipient Ferroelectrics
AIP Conference Proceedings, 2002We consider the quantum properties of mixed incipient ferroelectrics with small concentrations of ferroelectricity inducing ions such as KTa1−xNbxO3. We show that the nonuniform strong intra‐band electron ‐ phonon interaction leads to the localization of virtual conduction band electrons around the Nb ions and to the off ‐center displacements of these ...

Ferroelectric Tunnel Memristor
Nano Letters, 2012Strong interest in resistive switching phenomena is driven by a possibility to develop electronic devices with novel functional properties not available in conventional systems. Bistable resistive devices are characterized by two resistance states that can be switched by an external voltage.

A general description of the phenomena of ferroelectricity is given together with a brief history of the subject. A comparison is made between ferroelectricity and ferromagnetism. Next, a more detailed description is made of the properties of the three main types of ferroelectrics:the barium titanate, KDP (potassium dihydrogen phosphate), and Rochelle ...
