Reconstruction of steps on the Si(111)2×1 surface
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 -bonded reconstruction of the step edge is deduced from the images. © 1987 The American Physical Society.
