Structural and Chemical Evolution of l-Cysteine Nanofilm on Si(111)-√3×√3-Ag : From Preferential Growth at Step Edges and Antiphase Boundaries at Room Temperature to Adsorbate-Mediated Metal Cluster Formation at Elevated Temperature
The interaction of cysteine molecules with the Si(111)-√3×√3-Ag surface has been investigated over the submonolayer to multilayer regime using X-ray photoelectron spectroscopy, scanning tunneling microscopy, and density functional theory calculations. With both upper step and lower step terraces, st...
