Abstract
The structure of steps on cleaved silicon (111) surfaces is studied by scanning tunneling microscopy. Predominantly [21¯1¯] oriented steps are observed. Ordered regions of individual steps have unit periodicity along the step edge. A π-bonded reconstruction of the step edge is deduced from the images.Keywords
