A study was made of the dynamic behavior of atoms at step edges, and on stepped surfaces. Adatom diffusion on the terraces of (113) and (331) surfaces was studied and was found to be described by:

(113):     D (cm2/s) = 1.0 x 10-3 exp[-0.72(eV)/kT]

(331):     D (cm2/s) = 1.3 x 10-2 exp[-0.91(eV)/kT]
