Thermoelectric Mechanism of Field Emission from Carbon Nanostructures

Resumo

A model describing peculiarities of field emission from carbon nanomaterials is considered. The model is based on inclusion by drag of electrons by ballistic phonons in the temperature gradient range in the emission center. The model does not require any additional assumptions concerning a special energy structure of the emission center. Quantitative estimates of the thermopower coefficient obtained based on the emission model are in good agreement with experimental results.
