چکیده
Ferroelectric Bi2FeCrO6 (BFCO) double perovskite thin films were grown by pulsed laser deposition on SrTiO3 (111) covered with a 20 nm thick La2/3Sr1/3MnO3 buffer layer. X-ray diffraction measurements performed in θ-2θ and φ scans modes reveal an epitaxial growth of the BFCO compressive in-plane strained structure no spurious phases. The presence superstructure peaks indicates Fe-Cr cationic ordering along axis. Local realized piezo-response force microscopy show asymmetric polarization switching respect to external bias voltage suggesting field. This agrees preferential ferroelectric observed upon local poling film opposite directions. findings can be importance for understanding relationship between atomic dynamics thin-films.

Growth, Structure, and Electronic Properties of Epitaxial Bismuth Telluride Topological Insulator Films on BaF2 (111) Substrates
Epitaxial growth of topological insulator bismuth telluride by molecular beam epitaxy onto BaF2 (111) substrates is studied using Bi2Te3 and Te as source materials. By changing the beam flux composition, different stoichiometric phases are obtained, resulting in high quality Bi2Te3 and Bi1Te1 epilayers as shown by Raman spectroscopy and high-resolution X-ray diffraction. From X-ray reciprocal s...
