Phase transition on stepped silicon surfaces
Mashanov V.I. , Ol'shanetskii B. Z.
Phase transitions are discovered on clean silicon surfaces inclined away from (111) toward [2ΪΪ] planes. At temperatures below 850 °C, systems of ordered steps with height equal to three interplanar distances dlU9 which reform reversibly into steps with height equal to a single interplanar distance above 850 °C, form on such surfaces.
