Combining scanning tunneling microscopy (STM) and X-ray photoelectron (XPS) as well as Auger spectroscopy, we establish a direct relationship between the morphology and the excitation spectra of ultrathin MgO(0 0 1) films on Ag(0 0 1), and we show that monolayer MgO(0 0 1) films do not exhibit significant morphology changes upon H2O dosage, with the constituent islands remaining monoatomically flat up to exposures of tens of Langmuir.

Abstract
Combining scanning tunneling microscopy (STM) and X-ray photoelectron (XPS) as well as Auger spectroscopy, we establish a direct relationship between the morphology and the excitation spectra of ultrathin MgO(0 0 1) films on Ag(0 0 1), and we show that monolayer MgO(0 0 1) films do not exhibit significant morphology changes upon H2O dosage, with the constituent islands remaining monoatomically flat up to exposures of tens of Langmuir.
