Some articles on ferroelectric, ferroelectrics:

Ceramic Capacitor - Electrical Characteristics - Microphony
... All ferroelectric materials exhibit piezoelectricity, and have a piezoelectric effect ... Because class 2 ceramic capacitors using ferroelectric ceramics as dielectric, these types of capacitors may have electrical effects called microphonics ... Mechanical forces coming from shocks or vibration may be absorbed by the ferroelectric dielectric changing the thickness a little bit, and moving the distance of the electrodes to each ...
Mechanisms For Ferroelectricity in Multiferroics
... We can distinguish between proper and improper ferroelectric (FE) ... leads to ferroelectricity In the case of proper FE, the primary order parameter is the ferroelectric distortion ... In usual perovskite-based ferroelectrics like BaTiO3, the ferroelectric distortion occurs due to the displacement of B-site cation (Ti) with respect to the oxygen ...
Ferroelectric Capacitor
... Ferroelectric capacitor is a capacitor based on a ferroelectric material ... Ferroelectric devices are used in digital electronics as part of ferroelectric RAM, or in analog electronics as tunable capacitors (varactors) ... In memory applications, the stored value of a ferroelectric capacitor is read by applying an electric field ...
Implementations - Ferroelectric Memristor
... The ferroelectric memristor is based on a thin ferroelectric barrier sandwiched between two metallic electrodes ... Switching the polarization of the ferroelectric material by applying a positive or negative voltage across the junction can lead to large resistance variations over two orders of magnitude ... The reversal occurs gradually through the nucleation and growth of ferroelectric domains with opposite polarization ...
Nvram - Electrically Addressed - Ferroelectric RAM (F-RAM)
... Ferroelectric RAM (FeRAM, F-RAM or FRAM) is a random-access memory similar in construction to DRAM but (instead of a dielectric layer like in DRAM) contains a thin ...
