Electronic structure reconstruction and possible charge-transfer behavior in Sm-substituted trilayer nickelates
The trilayer Ruddlesden-Popper-type rare-earth nickelates, Ln4Ni3O10, have attracted considerable attention because of their superconductivity and density-wave (DW) behavior. The investigation of the interaction among these properties demands lattice and electron structure modulation. In this work, a series of Sm-doped...
