FIELD EMISSION OF CARBON NANOSTRUCTURES

Electron emission from solids, discovered in 1897 by W. Wood and theoretically substantiated in 1928 by the Fowler-Nordheim model, has become an integral attribute of modern solid-state electronics. For almost 100 years, the Fowler-Nordheim model has been supplemented many times and continues to this day (Kleshch V.I., 2024). All proposed models have one drawback: they do not take into account the size and properties of the surface layer of a solid, which is a quantum nanostructure at any temperature. In the proposed article, electron emission begins with a surface layer subjected to significant elastic stresses due to surface reconstruction. These deformations lead to the emergence of deformation energy, which, under external influence, is partially converted into heat, acoustic emission, field emission of electrons and luminescence. The essence of autoelectronic (field) emission is the emission of electrons by a solid body when exposed to an external electric field. In order for this emission to occur, the electron must overcome the potential barrier that holds the electron with the crystal field. We will consider the deformation energy as the potential barrier of a solid body. The essential difference of our model is that it allows us to theoretically calculate the threshold of autoelectronic emission of electrons from a solid body. We have shown that α-carbyne fibers should be used as an emitter instead of nanotubes. We will call the proposed model the diode model.
