Energetics of atomic hydrogen diffusion on Si(100). Vittadini, A., Selloni, A., & Casarin, M. Surface Science Letters, 289(3):L625–L630, June, 1993.
Paper doi abstract bibtex \textlessp\textgreater\textlessbr/\textgreaterWe present first principles calculations of the potential energy surface for the diffusion of a single hydrogen atom on Si(100)2 × 1. Surface relaxation is found to be very important for the energetics of diffusion. A strong anisotropy is predicted for hydrogen motion: H should diffuse mainly along dimer rows, where activation energies are ~ 1.3 eV, while the barrier for row-to-row hopping is ~ 0.5 eV higher. Our results indicate that diffusion can be considered a fast process compared to H2 recombinative desorption.\textless/p\textgreater
