Infrared spectroscopy experiments using CO as a probe and X-rayphotoelectron spectroscopy were used to study the initial nucleation of gold on the surface of MgO(001)/Ag(001) thin films at 90 K. The most intense CO infrared signal observed at low gol

The formation of Pd dimers on the surface of MgO has been studied by means of density functional theory (DFT) cluster model calculations. The following surface sites have been considered: regular five-coordinated anions at the (100) terraces, monoato
