Crystal–liquid interface energy and surface stress of alkali halides

A model to determine surface stress (f) and crystal–liquid interface energy (γ) of (1 0 0) face of NaCl type alkali halides without free parameters is established. While the predicted γ values are thermodynamically reasonable, the model predictions on f are in agreement with other theoretical calculations for (1 0 0) face of NaCl type alkali halides.
