Roughening of a growing surface on a crystal with correlated disorder: influence of nonlinearity
arXiv:cond-mat/9702096 · doi:10.1103/PhysRevE.55.6459
Abstract
We study the growth of a crystal in presence of a correlated disorder on the substrate. Using functional renormalization group, we show, for a long range disorder correlation, an initial decay of the KPZ type nonlinearity, though over a large length scale the behavior can be governed by the nonlinearity.
