Faceting through the propagation of nucleation.
Hyeong-Chai Jeong; Weeks, J.D.
Experiments show that faceting of a vicinal surface can be induced by
surface reconstruction, which often occurs only on sufficiently wide
terraces. We study this process using a one-dimensional terrace-step model
that assigns a lower free energy to terraces wider than a critical width
w/sub c/. When mass is conserved locally, through surface diffusion, we
find that a reconstructed terrace can nucleate the growth of another such
terrace nearby. The dynamics and spatial distribution of facets arising
from this model are very different from that produced by conventional
