Origin of abnormal structural transformation in a (BiPb)FeO₃/SrRuO₃/SrTiO₃ hetero-structure probed by Rutherford backscattering.

ABSTRACT: Scientific efforts are growing to understand artificial BiFeO₃/SrRuO₃/SrTiO₃-heterostructures, wherein an altered environment at each interface, caused by epitaxial strains, broken symmetry, off-stoichiometry and charge transfer, can generate a rich spectrum of exotic properties. Herein, (BiPb)FeO₃/SrRuO₃/SrTiO₃-heterostructures were sputtered with various top (BiPb)FeO₃-layers at different growth temperatures (T _g). Strain relaxation at each interface changes with T _g and generates an additional peak alongside with (BiPb)FeO₃ at a high T _g of 700 °C. Rutherford backscattering (RBS) was employed to understand this unusual behavior as to whether it is a mixture of two pha
