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.

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 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.

Ferroelectric means that the material has ... The MLU team irradiated the cell with laser light to test the new material, and the results surprised them. Compared to pure barium titanate of ...
