Controlled modification of individual adsorbate electronic structure

The controlled modification of the electronic structure on a single Mn adsorbate was addressed. This modification was achieved by placing the Mn atom within geometrical arrays of adatoms on Ag(111). The changes result from the coupling between the Mn s level and surface electronic states of the substrate. These surface states are scattered coherently within the adatom array, mediating the presence and shape of the array to the adsorbate within. The dimension and geometry of the adatom array thus provide a degree of control over the induced changes.
