Figure 3From: Tapered ZnO Whiskers: {hkil}-Specific Mosaic Twinning VLS Growth from a Partially Molten Bottom SourceSEM secondary electron images of Zn/W-ZnO particulates:a as-deposited by PLA, having W-ZnO condensates coalesced as NCA or in a closely packed manner on the surface of globular Zn particulates also in coalescence;b further annealed at 600°C for 30 min to form tapered W-ZnO whiskers radiating from the coalesced particulates. The magnified image from the arrowed area (inset) shows a wide whisker base (underline) and smaller pores (circle) nearby (cf. text);c andd Point-count EDX spectra from the arrowed areas ina andb, respectively, showing more Zn counts from the Zn particulate overlaid with tiny ZnO condensates than the W-ZnO whiskersBack to article page
