(a) Electron diffraction pattern recorded along the [001] = [0001] zone axis and superimposed on the corresponding bright field TEM image of a lead dioxide particle. The triplets (a, b, c) and (a*, b* and c*) are, for the hexagonal unit cell, the direct and reciprocal basis vectors, respectively. (b) Focus on one of the kinks shown at the top of Fig. 7 ![]() ![]() ![]() |
