abstract = {A scanning tunneling microscopy/atomic force microscopy
study is presented of a kinetically driven growth
instability, which leads to the formation of ripples during
Si homoepitaxy on slightly vicinal Si(001) surfaces miscut
in [110] direction. The instability is identified as step
bunching, that occurs under step-flow growth conditions and
vanishes both during low-temperature island growth and at
high temperatures. We demonstrate, that the growth
instability with the same characteristics is observed in two
dimensional kinetic Monte Carlo simulation with included
Si(001)-like diffusion anisotropy. The instability is mainly
caused by the interplay between diffusion anisotropy and the
attachment/detachment kinetics at the different step types
on Si(001) surface. This new instability mechanism does not
require any additional step edge barriers to diffusion of
adatoms. In addition, the evolution of ripple height and
periodicity was analyzed experimentally as a function of
layer thickness. A lateral "ripple-zipper" mechanism is
proposed for the coarsening of the ripples. (C) 2002
