13. -2 is the ratio between the electromotive force F and the magnitude A of the step-step repulsion (see Ref. 10) and a = 0.382 nm is the value of the interatomic distance along the step edge normal to the [112̄] direction for a Si(111) surface.

17. Partial alignment is maintained since the corners of the tetrahedral like islands point towards the [112] direction and irregularly shaped platelets decorate step edges (see Refs. 15 and 16).

24. This is confirmed by the fact that, for each distribution, the distance between the first and the second set of peaks is ≈300 nm, in agreement with the island-island mean distance.
