Abstract
Thin ( 1-7 monolayer) well-ordered, disordered, and liquid Hg overlayers on Ag(100) have been investigated with angle resolved photoemission and low-energy electron diffraction. The well-ordered overlayers exhibit new electronic states as a result of the strained, cubic, overlayer crystallographic structure. The new electronic states depend upon the long-range crystallographic order of the overlayer, not simply the local crystallographic symmetry. The photoemission cross section and branching ratio of the 5d mercury states depends on the overlayer long-range crystallographic order and cannot be explained by photoelectron diffraction.
