      abstract     = {Three-dimensional (3D) equilibrium crystal shapes (ECS) of
                      Pb are utilized for the first time to determine absolute
                      surface free energies via a quantitative evaluation of the
                      measured ECS and published values of step free energies of
                      vicinal (1 1 1) surfaces. 3D images of Pb crystallites are
                      obtained by scanning tunneling microscopy at 323-393 K. Line
                      scans through high symmetry <1 1 0> azimuths are transformed
                      into an anisotropic relative surface free energy,
                      gamma(theta, T). The absolute surface free energy of Pb(1 1
                      1) is obtained from the limiting slopes, df(theta, T)/d tan
                      theta, of the orientation dependent f(theta, T) gamma(theta,
                      T)/ cos theta at the boundaries of the (1 1 1) facet,
                      located at theta = 0degrees. This value is 25.7 +/- 1.4
                      meV/Angstrom(2) or 440 +/- 22 mJ/m(2). Absolute surface free
                      energies of other low-index orientations, such as (1 0 0),
                      (1 1 0) etc. are calculated from the relative anisotropy of
                      gamma(theta)/gamma(1 1 1). It is found that surface free
                      energies of orientation (h k l), expressed in meV/atom,
                      scale with the number of bonds broken in forming such a
                      surface. Free energies of steps bounding other facets, such
                      as (1 0 0), (1 1 0), (1 1 2), (1 1 3) and (2 2 1), are
                      evaluated in the [0 1 (1) over bar] zone, using the
                      corresponding facet radii and the absolute surface free
                      energies of those facets. (C) 2002 Published by Elsevier
