Spontelectrics is a form of solid state

thin films A thin film is a layer of material ranging from fractions of a nanometer ( monolayer) to several micrometers in thickness. The controlled synthesis of materials as thin films (a process referred to as deposition) is a fundamental step in many ...

with some peculiar physical properties.

Properties

When laid down as thin films tens to hundreds of molecular layers thick, a range of materials spontaneously generate large electric fields. The electric fields can be greater than 10⁸ V/m. Spontelectric behaviour is intrinsic to the dipolar nature of the constituent molecules. The detection (in ~2009) of spontaneous electric fields in numerous solid films prepared by vapour deposition raises fundamental questions about the nature of disordered materials. David Field played a major role in the discovery of spontelectrics.
