On the nonlocal electron kinetics in s and p striations of DC glow discharge plasmas: II. Electron properties in periodic states
The spatial relaxation behavior of the electron gas acted upon by strongly modulated striation-like electric fields, typically occurring in s and p striations of dc neon plasmas, has been investigated on a kinetic basis in part I of this paper. These studies have clearly shown that th electron relaxation in the striationlike field leads to the establishment of an unambiguous spatially periodic state, which is characterized by large modulation depths and phase delays of the microscopic and macroscopic quantities with respect to the striationlike field. The present part gives a detailed analysis of these quantities in the established striationlike states. These investigations clearly reveal the distinctly nonlocal electron properties, which are especially pronounced in the s-type of striations. In addition, the kinetic studies are completed by analyzing the impact of the field modulation degree and the sensitive destruction of the resonance behavior of the electron gas when imposing slightly nonresonant electric fields.
