Probe Voltage

Atoms on the surface of solids are in the form of negative ions. To analyze the emission portrait of the crystal surface with scanning tunnel microscope with tungsten probe, voltage of not more than 2 V should by applied. Studied autoelectronic emission in scanning tunnel microscope is realized from one emission center. In scanning tunnel microscope, ponderomotor forces significantly distort of the surface structure of solid. Autoelectronic emission from the surface of solid is performed together with negative ions and Fermi level.

Good Agreement

A model describing the features of field emission from carbon nanomaterials is considered. The model is based on taking into account the effect of electron drag by ballistic phonons in the region of the temperature gradient inside the emission center. The model does not require any additional assumptions about the special energy structure of the emission center. Quantitative estimates of the thermopower coefficient, made on the basis of the emission model, are in good agreement with the experimental results.
