abstract = {The onset of pattern formation through exposure of Pt(111)
with 5 keV Ar+ ions at grazing incidence has been studied at
550 K by scanning tunneling microscopy and is supplemented
by molecular-dynamics simulations of single ion impacts. A
consistent description of pattern formation in terms of
atomic scale mechanisms is given. Most surprisingly, pattern
formation depends crucially on the angle of incidence of the
ions. As soon as this angle allows subsurface channeling of
the ions, pattern regularity and alignment with respect to
the ion beam greatly improves. These effects are traced back
to the positionally aligned formation of vacancy islands
through the damage created by the ions at dechanneling
locations.},
