Growth and morphological characterization of zinc nanoplates

Zinc nanoplates were grown using thermal evaporation without catalyst or template involved. Tunneling electron microscopy and selected area electron diffraction analyses showed that the plates were single crystals with either {0001 } or { 11-20} as basal surfaces. The morphological characteristics w...

Description
Summary:Zinc nanoplates were grown using thermal evaporation without catalyst or template involved. Tunneling electron microscopy and selected area electron diffraction analyses showed that the plates were single crystals with either {0001 } or { 11-20} as basal surfaces. The morphological characteristics were explained in terms of the intrinsic growth anisotropy of zinc, the surface energy of the nano-crystals, the size of the critical nucleus and the migration of the adatoms. Our results suggested a promising low-cost route for synthesis of pure zinc nanoplates which could be used as precursor for further preparing core-shell nanoplate structures.
