“…There is implicit experimental information for ⑀ 2 : from island shapes 18 and fluctuations 21 ␤͑0͒ = 220± 11 meV. Since related measurements showed 1 2 ⑀ 1 = −128 meV, we deduce ⑀ 2 = −92 meV if ⑀ RT is insignificant.…”

“…where , sometimes 10 called the "Ising parameter," is the bonding energy associated with the "severed half" of the NN lattice-gas bond. Since the NN lattice-gas energy ⑀ 1 is attractive ͑negative͒, and half of it is attributed to the atom on each end, it "costs" a positive energy =− 1 2 ⑀ 1 for each step-edge atom.…”

“…From the equilibrium shape of islands over a broad temperature range, Giesen et al 10 deduced that the free energy per lattice spacing in the maximally kinked directions is 0.27± 0.03 eV on Cu͕111͖ and slightly smaller, 0.25± 0.03 eV, on Ag͕111͖. Combining these results with Eq.…”

“…The formation of facets below the roughening temperature, and the Pakrovsky-Talapov predictions [26] for the edge shape (z(x)) of crystals have been demonstrated in a number of clean systems [27][28][29][30][31][32][33][34]. In addition to studies on 3D crystals, there has been substantial work on the 2D ECS of islands [15,[35][36][37][38][39]] to obtain the edge free energy, equilibrium edge fluctuations and decay kinetics.…”
