Abstract

Our experimental data show that a rather thin layer with inverted polarization at the +c-face strongly suppresses the pyroelectrically induced electron emission from LiNbO3 crystals. We assume that the microscopic electric field of pyroelectric positive surface charges increases a potential barrier to polarons moving toward the vacuum. The pyroelectrically induced electron emission provides a novel method of detecting thin surface layers with inverted polarization.
