Zero- and one-dimensional nanostructures on anIMG/IMGsurface

摘要

Zero- and one-dimensional nanostructures on the surface ofcompositionally graded, epitaxial layers on Si(100) single crystals produced by a self-organized relaxation process are reported. Post-growth atomically flat surfaces can be converted into ordered, long-range coherent networks of nanostructures by a simple heat treatment procedure. The choice of heat treatment leads to a range of structures from millimeter long, single plateaus to complex patterns with nanometer structures and spacings. The vertical dimensions can be controlled in the nanometer range by varying the thickness of thelayer.
