Twinning-induced ZnO bicrystalline nanobelts

摘要

ZnO bicrystalline nanobelts induced by three types of twinning have been synthesized by thermal evaporation method. The morphology and microstructure of the ZnO bicrystalline nanobelts have been studied by means of scanning electron microscopy, transmission electron microscopy and high resolution electron microscopy. <2113>/{2112} twinning-induced ZnO bicrystalline nanobelts are dominant in the product. ZnO bicrystalline nanobelts induced by <0111 >/{0112} and <0332>/{0113} twinnings take up low fraction of the product. High oxygen partial pressure favors formation of the ZnO bicrystalline nanobelts.
