DFT investigation of the adsorption of atomic hydrogen on a cluster-model graphite surface
The H-graphite interaction is studied for the first time in the framework of density functional theory. A coronene-like Ž . model of the 0001 graphite surface is considered. LSD and LSDqGGA results are presented for both a planar substrate and for considering substrate relaxation. Two adsorption regions separated by a barrier are found: a physisorption region ̊ ̊ around 3 A from the surface and a...

متن کاملDynamics of subsurface and surface chemisorption for B, C, and N on GaAs and InP.
Using Hellmann-Feynman molecular-dynamics simulations, we have investigated interactions of firstrow elements with the (110) surfaces of GaAs and InP. We find that these atoms prefer to occupy subsurface sites. The open structure of the tetrahedrally bonded GaAs and InP, together with the small sizes of the first-row elements, makes it relatively easy for these atoms to move beneath the surface...

متن کاملScattering of O₂ from a graphite surface.
Recently an extensive series of measurements has been presented for the angular distributions of oxygen molecules scattered from a graphite surface. Incident translational energies ranged from 291 to 614 meV with surface temperatures from 150 to 500 K. The measurements were taken with a fixed angle of 90° between the source beam and the detector and the angular distributions consisted of a sing...
