Abstract
Pyroelectric electron emission current measure- ments and spatial electron current distribution collections were investigated from -Z face polar surface of lithium nio- bate monodomain crystals. The electron emission was detected during cooling due to a field ionization effect. The gap distance vari- ation between the crystal surface and the electron col- lector significantly influenced the emission behavior. For small gaps ( 2 mm) the pyroelectric electron emission was supplied from a soft and maintained plasma medium formation.
