Query: Step Bunching In Conserved Systems: Scaling And Universality   We study the step bunching process in three different 1D step flow models and
obtain scaling relations for the step bunches formed in the long times limit.
The first one was introduced by S.Stoyanov [Jap. J.Appl. Phys. 29, (1990) L659]
as the simplest 'realistic' model of step bunching due to drift of the adatoms.
Here we show that it could lead to (at least) two different types of step
bunching, depending on the magnitude of the drift. The other two models are
minimal models: the equations for step velocity are constructed ad hoc from two
terms with opposite effects - destabilizing and, respectively, stabilizing the
regular step train.
