The theory of surface dislocations is used to calculate the most likely deformation twinning plane in the diamond structure. The surface dislocation representing the twin boundary is assumed to correspond to one parallel array of like, glissile dislocations; that is a ‘simple glissile surface dislocation’. The treatment indicates that, in the diamond structure, deformation twinning of the first kind ought to occur on the {123} planes.
