Supplementary Figure 1

(a) An electrically conducting 2 mm-thick bulk ZnO substrate shows excellent optical transparency across the visible spectrum. The transmittance curves of other constituent materials used in MOA fabrication are also shown. Note that the ITO and polyimide are thin films; the oscillations in the transmittance of the polyimide film originate from optical interference, as expected in this thickness range for highly uniform films.
