Introduction and Experimental Considerations

The energy to produce a surface at a given temperature and pressure is the Gibbs surface free energy, G. The Gibbs surface free energy will be different for different facets of a crystal and is thus the key to determining the equilibrium crystal shape 

To see exactly how variations in G impact the equilibrium crystal shape of materials, let us now examine a simple two-dimensional model system. Consider 

A notable exception to the rule that experimental surface energy measurements are old is the experiments of Bonzel and coworkers on Pb in which surface free energies for individual crystal facets were determined from knowledge of the
