Abstract
Pyroelectric electron emission current measurements and current distribution collecting were performed on congruent and stoichiometric lithium niobate single crystals. Electron emission behaviors were found to be gap distance (crystal-detector) dependent. For small gaps, in both crystal compositions, emission was accompanied by a partial superficial domain inversion, triggered by surface plasma ignition. For large gaps (> 2 mm) in congruent single crystals the emission was activated by a true pyroelectric effect.
