Piezoelectric thin films of ZnO-nanorods/nanowalls grown by chemical bath deposition
This study presents a comparison of the piezoelectric properties of nanostructured thin films made of arrays of vertically oriented ZnO-nanorods (ZnO-NRs) over ITO-glass substrate and of ZnO-nanowalls (ZnO-NWs) over aluminium substrate. Both nanostructures were synthesized on a large area through chemical bath deposition. The morphological, structural, and chemical characteristics of the produced nanostructures were investigated in order to assess the crystal quality and purity.
