摘要

We report on the evolution of twin-coupled nanofinger structures in epitaxial Mn-doped Ba(Zr,Ti)O₃ films on a (001) MgO substrate. XRD studies showed that the films are highly c-axis oriented epitaxial films. TEM and high-resolution TEM studies showed that Mn:BZT films present a pseudo-cubic perovskite structure composed of an epitaxial layer near the interface followed by the formation of twin-coupled nanofingers. The epitaxial grains and the twin-couple domains coexist by sharing their {111} or {110} plane as a common plane. The transition from the epilayer to nanofingers is accomplished by alternatively introducing {111} and {110} plane twin boundaries. This particular process results in gradual reduction of the lateral size of the epitaxial grains and eventually drives the epitaxial structure into twin-coupled nanofingers. The possible atomic structure models for the {110} plane twin boundary are discussed.View full textDownload full textKeywordsTEM, epitaxial, oxide thin film, microstructure analysis, defectsRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/09500839.2011.562249
