NettetLecture 6 — Defects in Crystals. 1 Introduction In the first five lectures, we have focussed our attentions on the methodologies used to describe crystal symmetry and on the scattering techniques employed to study the arrangement of atoms and spins in crystals (electronic, nuclear and spin densities). Throughout this discussion, we NettetLine defects are called dislocations and occur in crystalline materials only. Dislocations are especially important in materials science, because they help determine the …
