The interaction between gold and oxides plays an important role in developing advanced materials for catalytic, photonic, and microelectronic applications. For example, Au/TiO2 [1] and Au/MgAl2O4 [2] show excellent catalytic activity and Au/CeO2 [3] has tunable reaction selectivity for energy-related reactions. Au/SrTiO3 interface [4] affects the tunneling probability, which is an important characteristic for device design. In spite of their technological importance, the microscopic nature of gold-oxide interfaces, primarily from the interaction between the delocalization of bonding electrons in gold and ionic bonds in oxides, is still a matter of debate.
