Eley-Rideal and hot atom reactions between hydrogen atoms on Ni(100): electronic structure and quasiclassical studies

Güvenç, Ziya B.; Sha, Xianwei; Jackson, Bret (Amer Inst Physics, 2001-11-15)

The reactions of gas-phase H (or D) atoms with D (or H) atoms adsorbed onto a Ni(100) surface are studied. Electronic structure calculations based on density functional theory are used to examine the interaction of H atoms ...
Kinetic model for Eley-Rideal and hot atom reactions between H atoms on metal surfaces

Jackson, Bret; Sha, Xianwei; Güvenç, Ziya B. (Amer Inst Physics, 2002-02-08)

A simple kinetic model is used to describe the interaction of H and D atomic beams with H- and D-covered metal surfaces. The atoms incident from the gas phase can have a direct Eley-Rideal reaction with an adsorbate, ...
The effects of lattice motion on Eley-Rideal and hot atom reactions: Quasiclassical studies of hydrogen recombination on Ni(100)

Güvenç, Ziya B.; Sha, Xianwei; Jackson, Bret (Amer Chemical Soc, 2002-08-22)

Quasiclassical methods are used to simulate the interactions of H or D atom beams with D- or H-covered Ni(100) surfaces. The Ni substrate is treated as a multilayer slab, and the Ni atoms are allowed to move. The model ...
