Nanoscale ferroelectricity is hard to characterize. Studies of BaTiO3 thin films now reveal a close coupling between the ferroelectric and the surface electrochemical states — a notion ...

Up until recently, researchers thought they had the behaviors of ferroelectric materials mostly figured out. “The conventional wisdom is that you can put almost any material under mechanical stress, ...

Studying ferroelectric materials can be done with the help of piezoresponse force microscopy (PFM), due to the sensitivity and nanometer-level resolution it inherits from AFM. Bruker discusses the ...

Ferroelectric materials are multifunctional materials that are irreplaceable in certain specific applications. They can be used in high-capacity capacitors, but they have low energy density.

The advantages of Hf0.5Zr0.5O2 The negative capacitance is a direct result of the intrinsic energy barrier between two stable polarization states of the ferroelectric layer, he says. In regular ...

Changing phase: antiferroelectric-to-ferroelectric phase transition. (Courtesy: Advanced Materials CC BY 4.0) Reduced beyond a certain size, antiferroelectric materials become ferroelectric. This new ...

HANGZHOU -- Chinese scientists have developed a highly-flexible and electrically-stable material that may effectively improve the performance stability of smart wearables. According to a study ...

A ferroelectric transistor that stores and computes at scale Date: July 13, 2023 Source: University of Pennsylvania School of Engineering and Applied Science Summary: Researchers have introduced a ...

Ferroelectric materials have switchable spontaneous polarization that can be reversed by an external electric field, which have been widely applied to non-volatile memory, sensing, and energy ...

FERROELECTRIC STUDIES AT FLEET Ferroelectric materials are keenly studied at FLEET (the ARC Centre of Excellence in Future Low-Energy Electronics Technologies) for their potential use in low ...

Researchers claim that using several very thin layers of ferroelectric crystals can lead to significantly better ferroelectric solar cell efficiency. But don’t pull the panels off your roof y… ...
