Predicting self-organization in DC glow microdischarges in different gases with the use of COMSOL Multiphysics

Summary form only given. Stationary self-organized patterns of cathodic spots have been observed in DC glow microdischarges in xenon
¹
. Recently, such patterns have been obtained in the numerical modelling
²
: multiple steady-state solutions have been found for the same discharge current, some of these solutions describing modes with a normal spot and other describing modes with several spots, which are qualitatively similar to those observed in the experiments
¹
and fit into the general pattern of self-organization in near-electrode regions
