Spontelectrics is a form of
solid state
Solid state, or solid matter, is one of the four fundamental states of matter.
Solid state may also refer to:

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.

When laid down as thin films tens to hundreds of
molecular
A molecule is a group of two or more atoms held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions which satisfy this criterion. In quantum physics, organic chemistry, and bioch ...
layers thick, a range of materials spontaneously generate large
electric fields. The electric fields can be greater than 10
8 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.
