摘要
The potential of an electrochemical cell has been found to vary periodically as Si/Si1-xGex superlattices are anodically etched at constant current. A simple anodic etching system has been used to characterise a range of structures, and both 5.6 AA germanium layers in silicon and 2.8 AA silicon layers in germanium have been resolved. A superlattice beneath a 0.5 mu m silicon layer has also been profiled, having removed the capping layer using a fast anodic etch.
