      abstract     = {In this study, the domain structure, bimodality of domains
                      and wedge-shape formation of domain tips are investigated in
                      tetragonal Pb[Zr0.375Ti0.625]O3 and Pb[Zr0.45Ti0.55]O3
                      ferroelectrics by transmission electron microscopy (TEM).
                      Finite element method (FEM) calculations predicted the
                      stability of the experimentally observed domain
                      configuration for different boundary conditions concerning
                      electrical as well as mechanical state. Detailed TEM studies
                      of a specific bimodal domain onfiguration, composed of four
                      different domains, revealed the presence of a domain wall
                      with alternating tiny head-to-side and tail-to-side arrays
                      and broad head-to-tail areas. The experimentally observed
                      existence of both, wedge-shaped domain tips and bimodality,
                      could be rationalized either by the presence of charges or
                      by shear stress as evidenced by FEM calculations.},
