Oxygen on Rh(100) revisited with ultra-high precision
We have reanalyzed the 0.25 and 0.50 monolayer (ML) phases of oxygen on the catalytically important Rh(100) surface by quantitative low-energy electron diffraction (LEED), variable-temperature scanning tunneling microscopy (STM) and density functional theory (DFT). For both phases, the crystallographic structure could...
