dc.description.abstract | We investigated the adsorption structures of serine on a Ge(100) surface by core-level photoemission spectroscopy (CLPES) in conjunction with density functional theory (DFT) calculations. The adsorption energies calculated using DFT methods suggested that four of six adsorption structures were plausible. These structures were the O-H dissociated-N dative bonded structure, the O-H dissociation bonded structure, the O(m)-H dissociated-N dative bonded structure, and the O(m)-H dissociation bonded structure (where O(m) indicates the hydroxymethyl oxygen). These structures are equally likely, according to the adsorption energies alone. The core-level C 1s, N 1s, and O 1s CLPES spectra confirmed that the carboxyl oxygen competed more strongly with the hydroxymethyl oxygen during the adsorption reaction, thereby favoring formation of the O-H dissociated-N dative bonded and O-H dissociation bonded structures at 0.30 and 0.60 ML, respectively. The experimental results were corroborated theoretically by calculating the reaction pathways leading to the two adsorption geometries. The reaction pathways indicated that the O-H dissociated-N dative bonded structure is the major product of serine adsorption on Ge(100) due to comparably stable adsorption energy. | - |
