Résumé

We have calculated the surface modes in Silicon at a (111)-surface. Apart from the long range limit, the modes depend strongly on the force constants in the first two layers near the surface. Special emphasis has been put on an investigation of soft surface modes. We find one mode which becomes soft very near the [MATH]-point which leads to a 7x7-superstructure.
