Combined transmission and reflection infrared microscopy and of scanning electron microscopy anodically etched (111) A surfaces showed extensive tunnel etch-pits and surface details in n-GaAs. Tunnel pits from anodic dissolution in flowing 10 percent aq. KOH occur in the dark or in the light at high anodic potentials when the current exceeds the saturation-value. Tunnel pits occur in dislocation-free material and may result from surface states created by preferential adsorption on (111)B faces. (WDM)
