      abstract     = {Equilibrium crystal shapes exhibit flat facets and rough
                      vicinal surfaces. with transitions between them being either
                      continuous or discontinuous, the latter recognizable by a
                      sharp edge. In general, mixed repulsive/attractive step-step
                      interactions may lead to continuous or discontinuous
                      facet-to-vicinal transitions. In can be shown that the
                      contact angle at the facet for a discontinuous transition is
                      directly related to the ratio of the step interaction
                      strengths. Alternatively, surface reconstruction of facets
                      can also be responsible for sharp edges at the facet
                      boundary. In this case the contact angle is related to the
                      difference between surface free energies of the
                      reconstructed and unreconstructed facet as well as the
                      corresponding difference of step interaction energies.
                      Fitting the experimental shapes by theoretical expressions
                      can be used to extract the relevant surface and step free
                      energies and also step interaction energies. Experimental
                      examples of Pb and Au equilibrium shapes are evaluated and
                      discussed. Step free energies of vicinal Au(1 1 1) and Au(1
                      0 0) surfaces, evaluated by both models, are 30 and 10
                      meV/A(2), respectively. (C) 2001 Elsevier Science B.V. All
