Simultaneous imaging of the piezoresponse phase, amplitude and bare surface topography of displacive ferroelectric thin films by scanning probe microscopy directly shows the nature of domain wall pinning and its relation to morphological disorder. Strong and stable pinning of walls occurs at grain boundaries while weak and unstable pinning occurs within the grains. The results show that polarization reversal consists of both nucleation of domains and spreading of domain walls, the latter being… Expand

TLDR
Three-dimensional objects undergo three kinds of stress: axial, radial, and azimuthal ('hoop stress'), the last of which has previously been ignored, and it is shown that it leads to w linear in d. Expand

Domain walls play an important role in pyroelectricity, as does the strain due to differential thermal expansion of pyroelectric films and substrates. In the present paper some new effects involvingExpand
