1.
Step edge diffusion and step atom detachment in surface evolution: ion erosion of Pt(111).
Michely, T; Kalff, M; Comsa, G; Strobel, M; Heinig, K H.
Phys Rev Lett ; 86(12): 2589-92, 2001 Mar 19.
Artigo em Inglês | MEDLINE | ID: mdl-11289987

RESUMO

The temperature dependent morphological evolution of Pt(111) under 1 keV Xe+ normal incidence ion bombardment has been investigated up to 600 monolayers removed. Coarsening of the surface structures during erosion and a qualitative change in roughness evolution between 650 and 700 K are found to be caused by different atomic processes: the former by diffusion of atoms along steps, the latter by the onset of step atom detachment.
