Abstract

Irradiation of EFG silicon in the 400kV HREM generates two kinds of radiation defects. The first kind are {113} planar faults. When a {113} defect encounters a twin boundary at an angle close to 80° the defect penetrates the boundary and continu es on the mirror symmetric {113} plane. Defects which encounter a twin band at an inclination of 30° are not able to penetrate the boundary. This difference can be explained by considering the size of the Burger’s vector of the residual defect left in the boundary. The second kind are {111} faults which appear as single defects or in groups in which the defects are offset relative to each other. The {111} defects are nucleated preferentially at or near the twin boundary. In narrow twins the/are observed to nucleate exclusively on the outside of twin bands but in wider twins they also form inside. This finding can be explained by considering the interaction between the interstitial, which is an extended defect and the twin boundary, which is a planar defect in which higher order nearest neighbor distances are reduced.
