Correlation between screening and electron effective mass across the nonmetal-metal transition in ultrathin films.

Core-hole screening as a probe for a metal-to-nonmetal transition in lead clusters.

Metal clusters serve as model systems to study basic problems of electronic correlation. Vacuum ultraviolet light from the free-electron laser FLASH ionizes 5d electrons from mass-separated negatively charged clusters, thus transiently leading to core-ionized neutral systems. Shielding of the core hole affects the electron binding energy. From the strong deviation from expectations of the metal...

Ultrathin composite films: An indispensable resource for nanotechnology

Ultrathin nanocomposite films were prepared on solid supports via adsorption of organic and inorganic molecules from solution. Coordination geometry for transition metal ions was preserved by embedding metal ligands into titanium oxide gel films, and porous titanium oxide films were prepared by selective removal of organic components from polymer/metal oxide composite films using oxygen plasma ...

Two-temperature nonequilibrium molecular dynamics simulation of thermal transport across metal-nonmetal interfaces

We have used a two-temperature nonequilibrium molecular dynamics method for predicting interfacial thermal resistance across metal-nonmetal interfaces. This method is an extension of the conventional nonequilibrium molecular dynamics for the dielectric-dielectric interface, where a temperature bias is imposed and the heat current is derived. We have included the electron degree of freedom for t...

Ultrathin oxide films on metal supports: structure-reactivity relations.

Well-ordered, thin oxide films have drawn some attention in recent years as suitable oxide supports for modeling highly dispersed metal catalysts at the atomic scale. It turned out, however, that ultrathin oxide films may exhibit interesting catalytic properties in their own right. In this review, we discuss phenomena specifically connected to ultrathin oxide films to explain and understand the...
