We have measured the terrace width distribution on copper (111) vicinal surfaces with (100) steps. For all surfaces, the distribution is well fitted by a Gaussian. The width of the Gaussian scales with the mean terrace width L, which is indicative of a repulsive 1/L2 interaction potential between steps. We determine an interaction strength of the potential of 3.2± 0.2 meV per atom length. From the temperature-dependent analysis of the step–step distance distribution, we find a kink formation energy for (100) steps of 0.12± 0.03 eV, which is consistent with previous measurements of the kink energy on copper (100) vicinal surfaces.

The height profile of a macrostep on a vicinal surface near equilibrium is studied numerically using a restricted solid-on-solid model with a point-contact-type step-step attraction (p-RSOS model). We calculate the surface tension of vicinal surfaces around the (001) surface inclined towards the111direction using the density-matrix-renormalization group method. We also calculate the height profiles of vicinal surfaces using the Monte Carlo method and study the connection between the height profile of the macrostep near equilibrium and the discontinuous surface tension. We find that the height profile of a macrostep on a vicinal surface near equilibrium can be classified depending on the zone in the faceting diagram where the system exists. We also find finite size effects both for the height profile and for the inhibition of the macrostep motion in the relaxation process to the equilibrium state.

We carried out reflection electron microscope (REM) observations of equilibrium shapes of Si(111) and (110) vicinal surfaces to estimate step creation energies and step interaction coefficients. A sample with a cylindrical hole was annealed at 1050°C under AC or DC heating. We measured widths of the facet surfaces and step positions on the vicinal surfaces and estimated the ratios of the step creation energies (B) and the step interaction coefficients (g) of these surfaces. We found that repulsive step–step interaction was stronger on the (110) surfaces than on the (111) surfaces, effective repulsive step–step interactions on both surfaces annealed by DC heating were stronger than those on surfaces annealed by AC heating, and the DC heating effect appeared more strongly on the (111) surfaces than on the (110) surfaces.
