A Study on the Stoichiometry of One-Dimensional Nanostructures

Figure 1

(a) and (e) Representative SEM images of mats of ZnTe nanowires grown in different runs but with the same growth parameters. The source and substrate temperatures were 750°C and 500°C, respectively. (b) and (f) Higher magnification SEM images of single ZnTe nanowires having various diameters. (c) and (g) The elemental distribution of ZnTe nanowires obtained from EDX analysis shown in (d) and (h).
