Generation of an amorphous phase on surface of LiF by thermoelectric effect and its crystallization

摘要

Influence of an electric field and simultaneous heating on a condition of {0 3 5 }, {110} and {111} crystal surfaces of LiF was investigated. It was shown that the effect resulted in structural changes shown as a jelly uncertain form formations. Generation of the amorphous phase was caused by the change of stoichiometry and accumulation of a charge in superficial layers. Fast growth of crystals is a result of photoeffect. Crystallization of neoplasm at seasoning in full darkness is caused by a relaxation of a volumetric charge and restoration of stoichiometric structure.
