Abstract
On the surface of the main crystal, positive ions interact with a negative cloud of free electrons and turn into neutral atoms. Neutral atoms having affinity to the electron other than zero additionally capture the electron and become negative ions. It is shown that under the action of ponderomotive forces the crystal surface is noticeably deformed, and it is experimentally confirmed. Besides, it is experimentally proved that three-atomic molecules possess allotropy in distribution of the built-in electric moments. The analysis of different physical models, which describe the thermo-and auto-electric emission of free electrons, is carried out and their inconsistency is shown. Thermal electron and field emission arise due to the temperature population of negative ions on the crystal surface and cluster vibrations in the near-surface layer. Field emission is thermal electron emission from negative ions and the Fermi level, which is transformed due to the action of the external electric field on the work of the surface by ponderomotive forces.
