Physics:Spontelectrics
From HandWiki
Spontelectrics is a form of solid state thin films 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.[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]
