| Inhoud: |
Epitaxial lead zirconate titanate nanoislands were obtained by a self-patterning method using the instability of ultrathin films during high-temperature treatments. After high-temperature annealing, the as-deposited film breaks into islands with a narrow size distribution. Nanostructures, as small as 20 nm lateral size with a height of 9 nm, were epitaxially grown on Nb-doped (001) SrTiO3 substrates. The formation of nanostructures was investigated as a function of the initial film thickness and crystallisation condition. Single-crystal nanoislands were studied by scanning and high-resolution transmission electron microscopy, atomic force microscopy and X-ray diffraction. Ferroelectric switching of several individual islands was investigated by piezoresponse force microscopy. |
