Strukturelles Design auf der Nanometerskala

Autor: Meyer, Dirk C., Paufler, Peter, Pompe, Wolfgang

Publikováno v: Wissenschaftliche Zeitschrift der Technischen Universität Dresden 56(2007)1-2, S. 100 - 104

For numerous technical applications, condensed materials must be specifically produced and manipulated on the nanometre scale. This frequently means the creation of an order with characteristic lengths in the range of extension of single atoms. Besid

Report

Dissociative adsorption of methane on surface oxide structures of Pd-Pt alloys

Autor: Dianat, Arezoo, Seriani, Nicola, Ciacchi, Lucio Colombi, Pompe, Wolfgang, Cuniberti, Gianaurelio, Bobeth, Manfred

Publikováno v: J. Phys. Chem. C, 2009, 113 (50), pp 21097-21105

The dissociative adsorption of methane on variously oxidized Pd, Pt and Pd-Pt surfaces is investigated using density-functional theory, as a step towards understanding the combustion of methane on these materials. For Pd-Pt alloys, models of surface

Report

Ab initio study of element segregation and oxygen adsorption on PtPd and CoCr binary alloy surfaces

Autor: Dianat, Arezoo, Zimmermann, Janina, Seriani, Nicola, Bobeth, Manfred, Pompe, Wolfgang, Ciacchi, Lucio Colombi

Publikováno v: Surface Science 602 (2008) 876-884

The segregation behavior of the bimetallic alloys PtPd and CoCr in the case of bare surfaces and in the presence of an oxygen ad-layer has been studied by means of first-principles modeling based on density-functional theory (DFT). For both systems,

Report

On the Short-Time Compositional Stability of Periodic Multilayers

Autor: Hentschel, Martina, Bobeth, Manfred, Diener, Gerhard, Pompe, Wolfgang

Publikováno v: Thin Solid Films 354 (1999) 267-275

The short-time stability of concentration profiles in coherent periodic multilayers consisting of two components with large miscibility gap is investigated by analysing stationary solutions of the Cahn-Hilliard diffusion equation. The limits of the e
