摘要
A method is presented for separating ''bulk'' and ''surface'' contributions to the strain derivative of the total energy of a two-dimensionally periodic, several-layer slab. The method, involving a layerwise decomposition of the sums and integrals required to calculate the derivative, makes it possible to compute a surface stress via a single, linear combination of atomic orbitals slab calculation. Application to Al(111) yields a predicted tensile surface stress of magnitude 0.090 eV/angstrom2.
