Identification of O-rich structures on platinum(111)-supported ultrathin iron oxide films

Strain-induced water dissociation on supported ultrathin oxide films

Controlling the dissociation of single water molecule on an insulating surface plays a crucial role in many catalytic reactions. In this work, we have identified the enhanced chemical reactivity of ultrathin MgO(100) films deposited on Mo(100) substrate that causes water dissociation. We reveal that the ability to split water on insulating surface closely depends on the lattice mismatch between...

Ultrathin, ordered oxide films on metal surfaces.

Metal oxides and oxide thin films are extensively used as active catalysts and catalytic supports, as well as in many other important technical applications. Unlike TiO(2), which is a semiconductor and can be investigated using a variety of surface science techniques, most metal oxides are insulators, which seriously restricts their use as model surfaces with modern surface science techniques. ...

Synthesis and Preparation of Oxide Ultrathin Films

There is a steadily growing interest in the research on oxide surfaces and films, due to their challenging fundamental properties and to their actual and potential applications in catalytic systems, chemical sensors, electronic and magnetic devices, and functional and aesthetic coatings. Special efforts have been directed at the study of ultrathin oxide films [1–11]. Such two-dimensional system...

Growth of ultrathin cobalt oxide films on Pt(111)

Ultrathin oxide films on metals: new physics and new chemistry?

Oxide thin films on metals are now currently used as model systems to study the surface properties of highly insulating oxides by means of electron spectroscopies. However, it has been recently proposed that ultrathin oxide films and oxide–metal interfaces may actually have unprecedented intrinsic chemical–physical properties, because of image potential screening of charge fluctuations and inte...
