Microstructure of undoped A-ZnO microtubes.
(a) HRTEM micrograph and corresponding FFT from the rectangular region of a single A-ZnO microtube (as marked in the inset). (b) XRD pattern of powdered A-ZnO microtubes. (c) Unpolarised Raman spectrum for backscattering perpendicular to the c-axis of the A-ZnO microtube.
