abstract = {Ripple patterns forming on Pt(111) due to 5 keV Ar+
grazing-incidence ion bombardment were investigated by
scanning tunneling microscopy in a broad temperature range
from 100 to 720 K and for ion fluences up to 3x10(20)
ions/m(2). A detailed morphological analysis together with
molecular dynamics simulations of single ion impacts allow
us to develop atomic scale models for the formation of these
patterns. The large difference in step edge versus terrace
damage is shown to be crucial for ripple formation under
grazing incidence. The importance of distinct diffusion
processes-step adatom generation at kinks and adatom lattice
gas formation-for temperature dependent transitions in the
surface morphology is highlighted. Surprisingly, ion
bombardment effects like thermal spike induced adatom
production and planar subsurface channeling are important
for pattern ordering.},
