In the experimental part we report on a typical bifurcation scenario of the current distribution in the discharge plane of a planar dielectric barrier discharge system. Increasing the amplitude $\hat U$ of the sinusoidal driving voltage after breakdo

In this article we deal with the experimental investigation of pattern formation in a planar ac gas-discharge system with a dielectric barrier. We report on the first observation of the transition from bright to dark current filaments and vice versa

The total current-voltage characteristics of the p+-n+-p-n− and n+-p-n-p− diodes under investigation show branches of negative differential resistance. Accompanied by the appearance of negative differential resistance is a filamentation of curren

In this Letter we report on the division of electrical current filaments in a planar semiconductor gas-discharge system with high ohmic electrode that we refer to as dissipative solitons. The effect is observed for stationary and propagating, as well

Self-sustained current oscillations in a Townsend discharge that is excited in a short plane discharge gap and is uniform along the electrode surface are investigated experimentally. A thin semiconductor plane serves as a discharge cathode, a ballast

In an ac-driven planar barrier gas-discharge system we observe solitary structures in the luminescence radiation density and the related current distribution that exhibit rather irregular motion. Using a stochastic data analysis, it can be demonstrat

Pattern formation in a gas discharge operating on the left-hand branch of the Paschen curve (obstructed discharge) is investigated. Such a discharge (in contrast to that operated on the right-hand branch) has a monotonic current–voltage characteris

The spatial and spatio-temporal patterning of the luminance distribution in laterally extended dc-driven gas-discharge systems with a semiconductor high-ohmic electrode is investigated. It is experimentally verified that a primary instability, via wh

The subject of this paper is self-organized solitary current filaments being observed experimentally in a planar dc gas-discharge system with high-ohmic barrier. We report on the dynamical behavior of these objects which we refer to as dissipative so
