Ordered two-dimensional arrays of silver adatoms with tunable metal atom density stabilized by 1,4-diethynyl-2,5-dimethylbenzene, a terminal alkyne, were prepared on Ag(111) and scrutinized by scanning tunneling microscopy and density functional theory calculations. Stabilization of the adatom arrays was attributed to the substrate-mediated electron localizations of the Ag adatom and terminal alkynyl in the molecule.
通过终端炔烃1,4 - 二乙炔基 - 2,5 - 二甲基苯在Ag(111)上制备了具有可调金属原子密度的有序二维银吸附原子阵列,并通过扫描隧道显微镜和密度泛函理论计算进行了仔细研究。吸附原子阵列的稳定性归因于分子中Ag吸附原子和终端炔基的底物介导电子定位。
