Figure 3: Thickness and size relation to Zn2+ concentration distribution.
From: Nanometre-thick single-crystalline nanosheets grown at the water–air interface
The blue shaded band represents a positively charged stern layer primarily composed of Zn2+ ions. The blue curve plots the concentration of Zn2+ from the end of the Stern layer (blue shaded area within the first 0.6 nm) into the bulk solution. The black triangles and red round dots marks the thickness of monocrystalline nanosheets and amorphous nanosheets formed prior, respectively, measured by atomic force microscopy (AFM). The right vertical axis is the side length of single-crystalline nanosheet triangles. It is noteworthy that the size of amorphous nanosheets are hundreds of micrometres and are not displayed in this plot.
