摘要：

Pyroelectrically induced electron emission (EE) is studied from LiNbO3 crystals with a layered domain structure fabricated under various diffusion treatments. It is observed that the appearance of a thin oppositely polarized surface layer at the +C-surface suppresses EE. For bidomain configuration with equal thicknesses of the inverted and the original domains EE occurs from the boundary between two domains. It is proposed that a potential barrier for emitted electrons depends strongly on the spontaneous polarization direction at a free polar surface,
