Sn-catalyzed thermal evaporation synthesis of tetrapod-branched ZnSe nanorod architectures.

A simple and reproducible Sn-catalyzed thermal evaporation synthesis of tetrapod-shaped ZnSe nanorod architectures was illustrated. The tetrapods were synthesized through thermal evaporation of a mixture of ZnSe, SnO, and activated carbon powders in a horizontal high-temperature resistance furnace. Detailed structural analysis of the ZnSe nanorod architectures was performed with high-resolution transmission electron microscopy (HRTEM) imaging and electron diffraction (ED). The surface of the branch is clean and abrupt on the atomic scale and no dislocations or stacking faults are observed along the branch length. The growth direction of the branch is parallel to the crystallographic axis and each branch of the complex anistropic nanocrystal grows parallel to its own unique axis but not along other directions. The results show that these architectures are intriguing objects for further exploration of advanced semiconductor nanodevices.
