Abstract

The origin of periodic electron spatial structures in gases subject to spatially uniform electric fields E0 has been recently analyzed through fluid equations [1] thereby providing greater physical understanding of the 'window' phenomenon in the Franck-Hertz experiment, and complementing the more accurate but purely numerical results provided by Boltzmann's equation [2]. Similar physical insight can be obtained for a spatially varying electric field, which modulates electron properties substantially if the applied wavelength matches the natural, 'Franck-Hertz' wavelength, simultaneously producing large phase shifts ('non-local effects'). Such cases have been analysed extensively through solutions of the Boltzmann equation [3] but never by physically tenable, benchmarked fluid modeling as described in [1, 4].
