New paper: Regioselective Growth Mechanism of Single Semiconductor Tips on CdS Nanorods
Regioselective growth of single tips onto CdS nanorods occurs under conditions that also favour longe-lived, metastable clusters and prevent growth of newly formed nanoparticles.
Our newest paper has just been published in Chemistry of Materials. In it, we show under which conditions it is possible to grow a single semiconductor tip on a specific facet of CdS nanorods. The key condition for tip growth is the existence of a sufficiently high barrier for the growth of new nanoparticles. These are the same conditions that, in the absence of seed particles, favour the formation of metastable, atomically defined magic-size clusters.
