9 Jan 2007 | | Subject: | Materials Science | | Abstract: | We propose a new method to control the roughness of a growing surface, via a time-delayed feedback scheme. As an illustration, we apply this method to the Kardar-Parisi-Zhang equation in 1+1 dimensions and show that the effective growth exponent of the surface width can be stabilized at any desired value in the interval [0.25,0.33], for a significant length of time. The method is quite general and can be applied to a wide range of growth phenomena. A possible experimental realization is suggested. | | Source: | arXiv, cond-mat/0701171 | | Services: | Forum | Review | PDF | Favorites | |
