摘要：

Knowledge of the surface stress anisotropy is a prerequisite for the description of the mesoscopic structure of stepped Si(001) surfaces. However, it is known that results from first-principles calculations for the (1 x 2) reconstructed surface surpass the experimental value by about a factor of 2. We demonstrate that this discrepancy is primarily not an extrinsic effect due to surface defects but a consequence of the elastic interaction between the dimers on the defect free surface.
