The growth of colloidal crystals of CdSe via controlled oversaturation is reported by these authors. In individual 3D quantum dot arrays formed in this manner, individual CdSe nanocrystals play the role of building blocks—artificial atoms in the next level of hierarchy (see also cover). Two different types of crystals— irregular and perfectly faceted hexagonal (see Figure)—can be prepared, depending on the speed of nucleation.
Talapin et al. (Sat,) studied this question.
