Pattern formation phenomena in current density distributions have been investigated experimentally in a dc-driven planar gas discharge semiconductor system. Patterns are observed and recorded via a light density distribution in the discharge gap, which can be seen through one of the electrodes. Under appropriate conditions the spatially homogeneous discharge glow undertakes a transition into hexagonal or striped patterns as the global current is increased.
