description: The subject of the present graduate qualification work is âEnlargement of antiferroelectric nanodomains at temperatures near the phase transition in epitaxial PbZrO3 thin filmsâ. Analysis of the size of antiferroelectric (AFE) domains of single crystal lead zirconate (PbZrO3) thin-films was carried out. Two films grown by pulsed laser deposition (PLD) with a thickness of 50 nm and 1000 nm at room temperature and 200 Â°C were studied by scanning with a nanofocused X-ray beam (X-ray nanoscopy). Estimates of domain sizes were obtained by characterizing the shape of obtained diffraction patterns (profile analysis of X-ray diffraction patterns). Initial observations of the scans (intensity maps) reveal that: the domain configuration of AFE domains in PbZrO3 epitaxial films has a granular character rather than a stripe-like domain configuration common in ferroelectric (FE) films. The absence of points with zero signal in the intensity maps indicate that a number of AFE domains are always on the path of the beam. As more than one domain may be found on the path of the beam, AFE domains are distributed through the volume of the sample. Obtained statistics of domain sizes for 50 nm and 1000 nm films at room temperature (RT) and 200 Â°C show that characteristic domain sizes for both films are almost equivalent (~ 13 nm). Thus, the characteristic size of AFE domains in epitaxial PbZrO3 films exhibits a thickness-independent behavior. At high temperatures ~ 200 Â°C, larger domains appear to be more stable than small domains. The discovered thickness-independent behavior indicates that the changes in thickness of AFE epitaxial films does not induce changes on the characteristic size of domains, contrary to the case of FE epitaxial films where a proportional correlation between thickness and domain sizes is observable.
