Fj. Williams et al., REPLY TO COMMENT ON STEP DYNAMICS AND EQUILIBRIUM STRUCTURE OF MONOATOMIC STEPS ON SI(100)-2X1, Physical review. B, Condensed matter, 56(23), 1997, pp. 15471-15473
Here we present the right way to extract interaction energies from dyn
amic measurements carried out for steps on Si(100)-2x1; this remains a
s an unsolved problem. The determined interaction energies agree with
those deduced via thermodynamic arguments from frozen patterns.
