“…Diffusion of silicon atoms and methoxylate adsorbates, redeposition of etched silicon from solution, and undercutting reactions were forbidden. The latter three assumptions are well justified for aqueous etching in the presence of alcohol, as discussed in refs – .…”

“…The rates of the site-specific reactions were user-controlled parameters that were determined by comparison to experimental morphologies. ,, On the basis of previous investigations of the reactivity of H/Si(111) in a variety of solutions, ,, five different reactive sites were included in the simulation: kinks, points, dihydride-terminated steps, monohydride-terminated steps, and terrace sites. Two additional reactive sites which must exist at least transiently during etching, trihydrides and strained horizontal dihydrides, have never been observed experimentally and were assumed to etch immediately upon formation.…”

Two solution-based strategies for the preparation of partially fluorinated Si(111) surfaces from H/Si(111) were investigated using a combination of scanning tunneling microscopy, X-ray photoemission spectroscopy, infrared spectroscopy, and kinetic Monte Carlo simulations. Direct fluorination of H/Si(111) with HF (aq) produced atomically flat surfaces with 11% fluorination. A two-step reaction that first methoxylated the surface by reaction in methanol and then converted the methoxy termination to F termination by reaction in HF (aq) produced atomically rough, fissured surfaces with 24% fluorination. The atomic-scale roughness was induced by the methoxylation reaction. Methanol was shown to react with H/Si(111) surfaces through two parallel mechanisms: an etching reaction and a methoxylation reaction. The methoxylation reaction locally inhibited or “frustrated” the etching reaction, leading to the development of a characteristic fissured morphology. The H and F atoms on the fluorinated surface were imaged with atomic resolution, and no evidence of the previously proposed nanopatterning mechanism was observed.
