“The new ferroelectric material – which is grown in the lab from cesium germanium tribromide (CsGeBr 3 or CGB) – opens the door to an easier approach to making solar cell devices,” they said.

that created a powerful solar energy producing effect. Ferroelectric means that the material has spatially separated positive and negative charges. The charge separation leads to an asymmetric ...

Research on ferroelectric materials shows that optimizing charge dynamics and reducing defects significantly improve ...

This is an artist's concept of optically-generated non-thermalized electrons and their collection in a ferroelectric crystal. An intense screening field results in impact ionization, enabling an ...

Despite this advantage, creating a hybrid material that could both switch its conductivity and maintain ferroelectric properties remained out of reach – until now. The material undergoes a remarkable ...

The bulk photovoltaic (BPV ... a quantum efficiency several orders of magnitude higher than other ferroelectric materials, ...

These PZT elements are used as ferroelectric capacitors, i.e. the ferroelectric material is the dielectric between the two plates, with a positive voltage storing a ‘1’, and vice-versa.

In a recent study published in Nature Nanotechnology, researchers from Rice University examined the behavior of relaxor ferroelectric materials, which are widely used in sensors, actuators, and ...
