A study at Rice University found that miniaturization of thin film material can open the door to a new generation of ...

As a ferroelectric relaxor, PMN-PT excels at converting energy from one form to another. For instance, pressing on a thin film of this material generates a voltage, while applying an external ...

They started with a piezoelectric PMN-PT crystal, added an ultra-thin layer of vanadium (ranging from 0.3 to 2 nanometers thick), and topped it with a layer of Co2FeSi (varying from 10 to 30 ...
