II-VI semiconductor nanocrystals have been extensively studied by soft chemistry methods. In addition to a control on the size, one has found modulation of the shape under various experimental conditions. This increases the surface area for similar sized objects and facilitates use in various applications such as catalysis where the increased surface area would imply more active sites. While experiments on hybrid perovskites have found only cubic facets, recently it was shown for CsPbX3 (X= Br,Cl) [1] that under certain experimental conditions one found a faceted polyhedron which could be transformed into a hexapod. We will present our recent theoretical studies which examine the stability of different facets and show how a shape modulation is possible [1].
