    • (private communication). Here is a simple argument: relatively unstable (stable) growth occurs whenever the nucleation of new islands on top of existing islands is enhanced (suppressed)compared to the situation with no step barriers. When EL=0 and EU>0, adatoms deposited on top of an existing island are hindered from attaching to the island's edge and thus are more likely to meet other adatoms to form a stable nucleus. Conversely, when EL=0 and EU<0, adatoms spend relatively less time on top of existing islands so that this renucleation probability is reduced. When EL>0 and EU=0, renucleation similarly is suppressed because deposited adatoms are hindered from joining a critical nucleus atop an existing nucleus. The reverse is true when EL<0 and EU=0 and the rate at which a critical nucleus converts to a stable nucleus by adatom attachment is enhanced.

    • We assume that overhangs are negligible as well since relaxing the SOS restriction is expected to yield λ != 0. See Ref. [24].
