Compressive strain-correlated PFM characterization of ZnO NS. (a) Amplitude and (b) PFM phase images of a ZnO NS obtained under four different compressive strain conditions. (c, d) Strain-related PFM amplitude (c) and phase (d) responses obtained using the image intensities extracted from selected small scan regions on the ZnO-NS surface. The shaded region represents the unstrained result.
