Spontelectrics

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.^[1]

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.^{[2][3][4][5][6]}
