Backdiffusion of electrons in nitrogen

摘要

Recently, back-diffusion has had a renewed interest due to its importance in practical plasma devices such as plasma light sources, display panels [1], in studies of breakdown [2,3] and in nuclear particle detectors [4,5]. Both kinetic theory [1] and Monte Carlo simulations [5] have been applied with some success. However it seems that the primary aim in those studies has been either to produce simplified formulae for application in plasma modelling [1 ] or to obtain an agreement with the experimental data [5] without analyzing which aspects of the process are required to achieve good representation of the phenomenon. In this paper we perform a systematic study of various models of most aspects of electron back-diffusion.
