Stripe Turing structures in a two-dimensional gas discharge system

Transition from Townsend to glow discharge: Subcritical, mixed, or supercritical characteristics

“…It follows immediately that for a bounded function with α(E) ≤ 1 for all E as in (6), the system size L needs to be larger than L γ L ≥ L γ (25) to sustain a stationary self-sustained discharge. This is true for arbitrary currents j and space charge effects.…”

“…Recently, the amazing variety of spatio-temporal patterns formed mainly in the transversal direction of a short dc driven system consisting of a gas discharge layer and a semiconductor layer sandwiched between two coplanar electrodes has drawn considerable attention [4][5][6][7][8][9][10][11][12]. These patterns are due to the nonlinear gas discharge being coupled to the linearly responding semiconductor.…”

Period doubling cascade in glow discharges: Local versus global differential conductivity

“…[2][3][4][5][6][7][8][9][10][11][12][13], a planar glow discharge layer with short length in the forward direction and wide lateral dimensions is coupled to a semiconductor layer with low conductivity. The whole structure is sandwiched between two planar electrodes to which a dc voltage U t is applied.…”

“…In comparison to the other systems, the glow discharge system has the advantage of particular convenient experimental handling and time scales [14]. In addition to structures familiar from other physical systems, glow discharges continue to exhibit new structures that might be specific for this system [2][3][4][5][6][7][8][9][10][11][12][13]. We will focus on the experiment in Ref.…”

“…An interesting series of experiments has been performed on such glow discharges with wide lateral extension [2][3][4][5][6][7][8][9][10][11][12][13] where the formed patterns were explored very systematically. The observed structures (stripes, hexagons, spirals, spots, homogeneous oscillations, etc.)…”
