    • Note
    • Yet in this case, instability of the growing surface may arise by the nonequilibrium contribution to the diffusion current due to the stochastic nature of the impinging flux. In the limit of ideal conserving MBE growth, surface diffusion provides the mechanism for describing roughening and scaling properties of the growth at a coarse-grained length scale.

    • Note
    • Generically, the adatoms moving on the surface acquire a systematic drift perpendicular to the direction of step edges (uphill/downhill current) due to an asymmetric rate of attachment and detachment that can be accounted for by different mechanisms. 11 14 The resulting current can either stabilize or destabilize the surface that consequently flattens or roughens.
