ANISOTROPY OF (1× 1)-SURFACE FREE ENERGIES OF CRYSTALS

1. IntroductionInterest in the surface free energy (SFE) of crystals is increasing as a consequence ofmodern experiments in the fields such as crystal growth, crystalline morphology, equilibra-tion of grain boundaries, sintering, adsorption and surface catalysis and .t.1--2].It is well known that the SFE of a crystal is generally dependent on the orientation ofthe surface3]. Some previous works have been done to calculate and measure the SFEl4--8].But, a generally theoretical method is s…
