Supramolecular ferroelectrics

Nature Chemistry, 2015
Supramolecular chemistry uses non-covalent interactions to coax molecules into forming ordered assemblies. The construction of ordered materials with these reversible bonds has led to dramatic innovations in organic electronics, polymer science and biomaterials.

Dielectrics and Ferroelectrics

2010
Despite the fact that the concept of the dielectric constant is often taught in introductory physics – because, e.g., of its applications to capacitors – the concept involves subtle physics. The purpose of this chapter is to review the important dielectric properties of solids without glossing over the intrinsic difficulties.

Binary Compound Bilayer and Multilayer with Vertical Polarizations: Two-Dimensional Ferroelectrics, Multiferroics, and Nanogenerators.

ACS Nano, 2017
Vertical ferroelectricity in two-dimensional (2D) materials is desirable for high-density data storage without quantum tunneling or high power consumption/dissipation, which still remains elusive due to the surface-depolarizing field.

Two-Dimensional Organic-Inorganic Hybrid Rare-Earth Double Perovskite Ferroelectrics.

Journal of the American Chemical Society, 2019
As a major branch of hybrid perovskites, two-dimensional (2D) hybrid double perovskites are expected to be ideal systems for exploring novel ferroelectric properties, because they can accommodate a variety of organic cations and allow diverse ...

Ferroelectrics and Antiferroelectrics

2006
Ferroelectric crystals (especially oxides in the form of ceramics) are important basic materials for technological applications in capacitors and in piezoelectric , pyroelectric , and optical devices . In many cases their nonlinear characteristics turn out to be very useful, for example in optical second-harmonic generators and other nonlinear optical ...

Ferroelectric-optical memory on ferroelectric thin films

Ferroelectrics Letters Section, 1994
Abstract New type memory on ferroelectric thin films is proposed. Writing of information is performed by localheating of the film by laser beam up to the Curie temperature or above and cooling the film in external electric field. Reading can be made by nondestructive methods including pyroelectricity, piezoelectxicity, birefringence, optical activity ...
