S. Mukherji, ROUGHENING OF A GROWING SURFACE ON A CRYSTAL WITH CORRELATED DISORDER- INFLUENCE OF NONLINEARITY, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 55(6), 1997, pp. 6459-6466
We study the growth of a crystal in the presence of correlated disorde
r on the substrate. Using a functional renormalization group, we show,
for a long-range disorder correlation, an initial decay of the Kardar
-Parisi-Zhang-type nonlinearity, though over a large length scale the
behavior can be governed by the nonlinearity.
