Morphology, crystal structure, and chemical composition. (a) Top-view and (b) side-view SEM images of the typical CdSe nanotube arrays on ITO/glass; the inset in (a) shows the magnified SEM image of a single nanotube (scale bar, 100 nm). (c) The XRD data of the sample (the diffraction peaks from the ITO substrate are marked with asterisks). (d) The TEM image, (e) the SAD pattern, and (f) the EDX spectrum taken from a single CdSe nanotube.
