Growth Instabilities Induced by Elasticity in a Vicinal Surface

  title={Growth Instabilities Induced by Elasticity in a Vicinal Surface},
  author={Christophe Duport and Paolo Politi and Jacques Villain},
We study the eifect of elasticity on the step-bunching mstability m heteroepitaxial growth on a vicinal substrate. Three main eifects are taken into account: the Schwoebel barrier and the step-step and the step-adatom elastic interactions. The first one is always stabilizing, the second one generally destabilizing and the last one, stabilizing or Dot according to the sign of the misfit with the substrate. At very low values of the flux F, Orly the step-step interaction is effective: the… CONTINUE READING
