M. Vladimirova et al., A new model of morphological instabilities during epitaxial growth: from step bunching to mounds formation, J CRYST GR, 220(4), 2000, pp. 631-636
We show that the theoretical description of the spontaneous evolution of an
epitaxially growing surface towards self-organised structures, changes qua
litatively when the simultaneous presence of several chemical species is ta
ken into account. In the framework of a two-particle model studied by Monte
-Carlo simulations we prove that a growing surface can exhibit step meander
ing, step bunching and mounding in different growth regimes, assuming only
positive Ehrlich-Schwoebel step-edge barrier. (C) 2000 Elsevier Science B.V
