Electric-Field Heating Threshold for Charged Particles

Abstract

In deriving expressions for the electrical conductivity in a gas, Kerrebrock, Cann, and others have recently recognized the importance of the elevated electron temperature to the conduction process. The present note attempts to point out that the role of the local electric field in maintaining the temperature difference ("nonequilibrium") between the electrons and the other species, and a threshold in the field strength below which the electronic (and ionic) mobilities are independent of field strength, can be derived from elementary considerations.
