Layer‐by‐layer growth of Hg on W(110)

Using photoelectron spectroscopy, the overlayer electronic structure was observed to be modulated by the Hg growth mode for Hg adsorbed on W(110) at 200 K. The Hg layer‐by‐layer growth was also characterized by variations in the ratio between the Hg 5d shallow core level and W 4f photoemission intensities. This layer‐by‐layer growth occurs in spite of surprisingly weak electronic interactions between the adatoms and the substrate.
