The work studies the transition from periodic to chaotic oscillations in a dc-driven planar gas discharge with a high-ohmic electrode. The applied voltage and resistance of the semiconductor layer act as control parameters. The oscillations occur in the subnormal discharge regime. The bifurcation diagram and Lorenz map characterizing transition of this system to chaos through period-doubling bifurcations are obtained. Numerical models employed are based on the drift-diffusion theory of gas discharges. The effect of two modelling approaches, namely the ‘simple’ fluid model and the more detailed ‘extended’ fluid model, is considered. The calculations showed that the results obtained by these two approaches are different in quantitative terms, however, qualitatively similar in terms of the dynamic behavior of the system as a function of the control parameters.

平面气体放电半导体系统中从周期性振荡到混沌振荡的转变

这项工作研究了在具有高欧姆电极的直流驱动平面气体放电中从周期性振荡到混沌振荡的转变。半导体层的施加电压和电阻用作控制参数。振荡发生在非正常放电状态。获得了分叉图和Lorenz映射,该分叉图和Lorenz映射表征了该系统通过倍频分叉过渡到混沌的过程。所采用的数值模型基于气体排放的漂移扩散理论。考虑了两种建模方法的效果,即“简单”流体模型和更详细的“扩展”流体模型。计算表明,这两种方法获得的结果在数量上有所不同,但是,
