Synthesis And Characterization Of Zns Bicrystal Nanoribbons
APPLIED PHYSICS LETTERS(2003)
摘要
Here, we report a form of nanostructures bicrystal nanoribbons. Zinc sulfide (ZnS) bicrystal nanoribbons were prepared via simple thermal evaporation of a powder mixture of ZnS and SiO. The product was characterized with transmission electron microscopy (TEM), high-resolution TEM, and electron energy loss spectroscopy. The ZnS bicrystal nanoribbons have widths of 50-500 nm and lengths of several tens of micrometers. Two kinds of growth direction, i.e. [-1-21] and [-1-31], have been found. The growth of the ZnS bicrystal nanoribbons was considered to involve a combination of oxide-assisted and vapor-liquid-solid processes. (C) 2003 American Institute of Physics.
