Abstract The mechanism of striations in dielectric barrier discharge in pure neon is studied by a two-dimensional particle-in-cell/Monte Carlo collision (PIC-MCC) model. It is shown that the striations appear in the plasma background, and non-uniform electrical field resulting from ionization and the negative wall charge appear on the dielectric layer above the anode. The sustainment of striations is a non-local kinetic effect of electrons in a stratified field controlled by non-elastic impact with neutral gases. The striations in the transient
dielectric barrier discharge are similar to those in dc positive column discharge.
