Abstract

We consider a non-linear version of Edwards-Wilkinson interface model for the growth in the presence of a collimated partjcie flux. We include both surface tension and surface diffusion relaxation. In a range of positive small values of the surface tension, the interface develops a state which fulfills standard criteria for spinodal decomposition. This suggests the existence of a phase transition from the ordinary state with the interface perpendicular to the incoming flux to a novel, noue.induced state with the interface apontaneously tilted with respect to the direction of the flux.

[10] The full non-linear surface tension term in (1) is somewhat different from the ro-t at ion ally invariant term arising from evaporation/recondensation processes, see Mullins, Ref. 1. However, both terms yield essentially the same physics. See L.Golubović and R. P. U.Karunasiri, submitted to J. Phye. (Paris). We note that a short version of this work appeared in Phys. Rev.
