DOI: 10.1103/PhysRevLett.92.0732010031-9007http://hdl.handle.net/10919/24492Self-assembled monolayers (SAMs) of carbonyl-containing alkanethiols on gold are employed to explore the influence of hydrogen-bonding interactions on gas-surface energy exchange and accommodation. H-bonding, COOH-terminated SAMs are found to produce more impulsive scattering and less thermal accommodation than non-H-bonding, COOCH3-terminated monolayers. For carbamate-functionalized SAMs of the form Au/S(CH2)(16)OCONH(CH2)(n-1)CH3, impulsive scattering decreases and accommodation increases as the H-bonding group is positioned farther below the terminal CH3.application/pdfenIn Copyrightself-assembled monolayerscollisionsau(111)chaingoldPhysicsArticle - Refereedhttp://link.aps.org/doi/10.1103/PhysRevLett.92.073201https://doi.org/10.1103/PhysRevLett.92.073201
