Atomic diffusion on the semiconductor surface:
Figure:
Top view shows the potential profiles and the corresponding pathways.
The circles indicate the energetics of the rebonded structure while
the squares do nonbonded structures. The lengths along [110] is in units
of A. The Es1 and Es2 are the first and second Schwoebel barrier,
respectively.
