Spatial patterns of a large-scale sheetlike current filament formed during low-fernperature avalanche breakdown have been investigated in a thin epitaxial n-GaAs layerusing the low-temperature scanning electron microscope. The sheetlike current filament was nucleated between planar-type ohmic contacts due to impact ionization ofneutral shallow donors. The width of the current filament (200 -700qm) wasmeasured as a function of the sample voltage in the postbreakdown regime. A furbulent pattern observed in the beam-induced firing wave instability has also beenmeasured.
