The intermetallic oxidation of Pd(100)

• We have studied the Pd(100)-(√5×√5)-O structure formed by adsorption of 0.8 ML of oxygen by Scanning Tunneling Microscopy (STM), High Resolution Core Level Spectroscopy (HRCLS) and Density Functional Theory (DFT). We show that a recent tensor Low Energy Electron Diffraction (LEED) analysis of the Pd(100)-(√5×√5)-O structure is incompatible with our results from this structure. A new model that is consistent with our results is suggested. We also demonstrate the existence of dislocations observed by STM in the Pd(100)-(√5×√5)-O structure and explain their geometrical arrangement
