First-principles study on the multiferroic BiFeO3 (0001) polar surfaces
JQ Dai, JW Xu, JH Zhu - Applied Surface Science, 2017 - Elsevier
We present first-principles DFT+U calculations to investigate the stoichiometric (0001) polar
surfaces of multiferroic R3c BiFeO 3. We predict that the complete Fe-O 3-Bi trilayer, which is …
