Crystals with (100) surfaces were studied, using conventional transmission electron microscopy, in order to relate their microstructure to their growth habits. The crystals were prepared using 2 different growth methods which gave slightly different results. The presence of dislocations of mixed character, that ended at only 2 surfaces, were responsible for tabular growth in both cases; but the formation of the dislocations was different. In the first case a stacking fault was formed, and eliminated by dislocations. In the second case, the incorporation of iodide impurities led to the formation of dislocations.
