Abstract
Bulk crystalline materials are annealed by introducing into them mechanical energy of sufficient intensity to create a large amplitude sound wave. The mechanical energy may be introduced into the material, for example, by laser ablation. Where the bulk crystalline material is a doped semiconductor, the process also electrically activates the material.
