Abstract
We investigate the vapor-phase nucleation of CdSe nanostructures on
nanocrystals seeds of different shapes. The growth dynamics is assessed
by transmission electron microscopy, following the evolution of the same
nanocrystals prior and after the deposition process. We prove that
individual nanocrystals can sustain the growth of single nanowires and
determine their final morphology. Straight or branched nanowires are
obtained from spherical or tetrapod-shaped nanocrystals, respectively.
When tetrapod-shaped nanocrystals are used, we also find that their
original shape and orientation are mostly preserved upon further growth.
