Special branch: Branched nanocrystals of CdS (tripods and tetrapods; see image) are obtained with a simple solvothermal process through inclusion of dopant Se or Te. This causes CdS to nucleate in the zinc blende phase instead of the typical wurtzite phase, from which the subsequent 1D growth of wurtzite arms leads to the formation of the branched structures.
