      abstract     = {The shapes of (111) oriented two-dimensional (2D) islands
                      and facets, the latter being part of three-dimensional (3D)
                      crystallites of Pb, were equilibrated at 104-520 K. Island
                      sizes were in the range of 15-90 nm radius, facets typically
                      at 100-270 nm radius. They were imaged by scanning tunneling
                      microscopy to provide the exact outline of the bounding
                      step. Increased step roughening with increasing temperature
                      decreases the radius anisotropy of islands and facets in a
                      consistent manner. Products of island/facet radius times
                      local step curvature versus temperature were obtained
                      experimentally, serving as the basis of absolute step and
                      kink energies at 0 K. They are f(1A)(0)=128.3+/-0.3 meV,
                      f(1B)(0)=115.7+/-5.8 meV, and epsilon(kA)=42.5+/-1.0 meV,
                      epsilon(kB)=60.6+/-1.6 meV, respectively. The combination of
                      studying small 2D islands (unstable at high temperature) and
                      large 2D facets allows measurements over a very large range
                      of temperatures.},
