Abstract
It is demonstrated, using reflectance difference spectroscopy, scanning tun neling microscopy, and low-energy electron diffraction, combined with delib erate straining of the surface, that the presence of atomic steps dramatica lly changes the optical anisotropy of the Si(001) surface. The step-induced reflectance difference signal originates predominately from rebonded steps and is comparable in magnitude to that of the terrace signal.
