Transmission electron microscopy has been used to investigate the character and distribution
of the microstructural features in epitaxial (001) ferroelectric PbZr0.2Ti0.8O3 films grown on (001)
SrTiO3 substrates by pulsed laser deposition. The TEM observations revealed that the films
were predominantly c-oriented with embedded a1- and a2-oriented domains lying on {101}
planes. The substrate/film interfaces contained arrays of edge-type misfit dislocations and there
were extraordinarily high densities ( 1010
