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 …

Surface segregation in strontium doped lanthanum cobalt ferrite: effect of composition, strain and atmospheric carbon dioxide

Y Yu - 2016 - open.bu.edu
Solid oxide fuel cells (SOFCs) convert chemical energy directly into electrical energy,
leading to significantly higher conversion efficiencies. The oxygen reduction reaction (ORR) …
