Structural Instability of Epitaxial (001) BiFeO(3) Thin Films under Tensile Strain
We explore BiFeO(3) under tensile strain using first-principles calculations. We find that the actual structures are more complex than what had been previously thought, and that there is a strong shear deformation type structural instability which modifies the properties. Specifically, we find that...
