{{short description|Production of electric fields by thin films of various materials}} {{confusing|date=June 2013|reason=The average user may have difficulty understanding what this article is about.}}

In solid state physics, '''spontelectrics''' is the study and phenomenon of thin films of various materials producing strong electric fields.

== 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 10<sup>8</sup>&nbsp;V/m.<ref>{{cite journal|last=Field|first=David |author2=O. Plekan |author3=A. Cassidy |author4=R. Balog |author5=N.C. Jones |author6=J.

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.<ref>{{cite journal|last=Plekan|first=Oksana|author2=Andrew Cassidy |author3=Richard Balog |author4=Nykola C.
