We introduce two hybrid models of step bunching on vicinal crystal surfaces. The model equations for step velocity are constructed by the two possible exchanges of terms between the equations of two primary models MM2 and LW2 [arXiv:1011.1863], both showing the specific type of bunching with minimal step-step distance lmin in the bunch independent of the number of steps N in it. This feature is preserved only in the hybrid model LW2MM (the first term in the model equation comes from LW2 and the…

Self-Organization on Unstable Vicinal Surfaces with Competing Interactions
Long-ranged step-step attractions destabilize the vicinal crystal surfaces. Their competition with shorter-ranged step-step repulsions results in self-organized patterns. The exponent in the
