Microscopic theory of molecular crystal surface polarization, piezoelectricity, and pyroelectricity

open access: yes, 1994
Nonpolar crystals must exhibit a surface polarization induced by the loss of bulk symmetry at the surface. For crystals of nonpolar molecules, the surface polarization is normally induced by incomplete cancellation of the electric fields of the molecular
