摘要：

Using low-energy electron microscopy we have found a new phase transition on the Si(001) surface at miscut angles smaller than approximately 0.1-degrees. The surface phase separates into facets with approximately 300 angstrom terrace width, and regions with much larger, wavy terraces. This wavy phase is stabilized by a reduction of surface-stress-induced strain energy. A theoretical study by Tersoff and Pehlke compares favorably with our observations.
