Step-and-terrace
網頁On coarse-graining, this translates into an effective stiffness or line tension that tends to keep the step straight. Standard microscopic 2D models of step arrays incorporating both of these physical effects include the free-fermion model and the Terrace- … 網頁This type of landscaping is therefore called terracing. Graduated terrace steps are commonly used to farm on hilly or mountainous terrain. Terraced fields decrease both erosion and surface runoff, and may be used to support …

網頁2008年9月30日 · The substrate surface exhibits step and terrace structures with root-mean square (RMS) roughness of around 0.12–0.16 nm. An arrangement of regularly spaced and nearly parallel steps was observed after just CMP treatment of 30 min, and the morphology was almost unchanged with increasing the polishing time. 網頁2024年9月26日 · Longer annealing leads to the formation of bunched terraces with large step heights of 1-5nm. The optimized recipe developed here efficiently removes surface adsorbates, namely hydroxyl and carbonate groups and restores the terraces on the surface. I. INTRODUCTION
網頁1987年1月1日 · The dynamics of site exchange between CO molecules chemisorbed on step and terrace sites has been investigated using temperature programmed desorption. Isotopically labeled CO molecules adsorbed on stepped sites have been shown to completely randomize with CO molecule adsorbed on terrace sites during the … 網頁2009年9月18日 · Various interesting phenomena related to the step-and-terrace structures of crystal surfaces have been previously observed. In this paper, we report a unique phenomenon not observed previously: the formation of a new class of step-and-terrace structure on the 4H-SiC (0001) surface after high-temperature gas etching.
