41th international conference on plasma physics and CF, February 10 – 14, 2014, Zvenigorod NUMERICAL STUDY OF NONLINEAR OSCILLATIONS AND PATTERN FORMATION IN GLOW DISCHARGE- SEMICONDUCTOR SYSTEM İ. Rafatov, İ. Uzun-Kaymak, S. Çakır Middle East Technical University, Ankara, Turkey, [email protected] We studied a system consisted of a planar glow discharge layer with short length in the forward direction and wide lateral dimensions, which is coupled to a semiconductor layer with low conductivity. The whole structure is sandwiched between two planar electrodes, to which a dc voltage is applied. Experiments show that such a system can create different homogeneous stationary and homogeneous oscillating modes, patterns with spatial and spatiotemporal structures. We developed and applied full three-dimensional fluid numerical code to study temporal and spatial pattern formation in this system. 1
