Abstract: We propose a simple model for estimating the nonlinear phonon drag contribution to thermopower generated by a heat flux propagating from a conductive nanoparticle into a semiconductor. The results of the study confirm that thermoelectric effect in nanostructured electron emitters can produce electric “patch field” patterns with magnitudes sufficient to significantly stimulate emission. The phenomenon predicted by the model can possibly be used to develop thermoelectric converters with unique parameters.

Keywords: thermoelectric effect, phonon drag, field electron emission, nanostructures, thin films.
