WebJun 10, 2013 · 2.1. Area-Selective ALD on SAM . Patterned SAMs are commonly used as growth-preventing masks for selective-area ALD. Selective-area ALD is the growth of thin films on the substrate surface on designated sites only. Selective-area ALD requires that the chosen regions of the surface are inert to ALD precursors. WebSelective adsorption of α,β-unsaturated aldehydes (α,β-UALs) is a prerequisite for the hydrogenation of α,β-UALs to high-value unsaturated alcohols, but a quantitative description of the interactions between the C═C/C═O bond of α,β-UALs and the catalysts is still lacking. Herein, based on comprehensive density functional theory calculations, we developed a …
