Self-organized nucleation of current-density filaments has been investigated in n-GaAs epitaxial layers with different concentric contact geometries by measuring the photoluminescence spatially resolved. While the first filament arises from a spatially uniform state, further filaments are generated by filament division processes. Filament growth and filament division of filaments reveal hysteretic behavior. In a magnetic field filament bending or destabilization of stationary patterns in favor of oscillating filamentary patterns occur.
