From: General Route to ZnO Nanorod Arrays on Conducting Substrates via Galvanic-cell-based approach

FESEM images and XRD patterns of ZnO nanorods grown on Pt-coated silicon wafers.
(a, c) FESEM images and (b) XRD patterns of ZnO nanorod arrays grown on Pt-coated silicon wafers (Pt/Si) with Al on the edge. The peaks marked with asterisks are associated with the substrate. (d) FESEM images and EDS of the product grown on Al region. (e) FESEM images of ZnO nanorod grown on Pt/Si without Al.
