Emission of electrons on switching of the Gd2(MoO4)3 ferroelectric-ferroelastic in electric field

Abstract

We have revealed an electron emission on the switching of extrinsic gadolinium molybdate ferroelectric-ferroelastic in electric field. Visualization of the electron flow allows directly watching of the domain structure dynamics: formation and growth of tapered domains and lateral movement of the 180° domain wall. We have found that the electron emission contributes substantially to the screening processes in the case of a crystal with free surface.
