A study of cleaved germanium surfaces by transmission electron microscopy and gold transfer replicas provides direct and indirect evidence of plastic deformation introduced by the cleavage process at room temperature. The results are interpreted as showing that dislocations move by glide on {111}‐type planes parallel to the surface and at 70°32′ to the surface. Experiments are also reported using copper plating as a technique for decorating surface damage.
