Probing the Local Chemical and Structural Ordering of Iron Oxyfluoride

Scanning transmission electron microscopy (STEM)-electron energy loss spectroscopy (EELS) has been used for studying local structure of the energy related materials. High resolution (Cs-corrected) STEM is regarded as a promising technique to observe morphological evolution and atomic arrangement inside single particles. Combining with EELS technique, one could probe the local chemical structure...

Electronic and magnetic reconstructions in manganite superlattices

We investigate the electronic reconstruction at the interface between ferromagnetic metallic (FM) and antiferromagnetic insulating (AFI) manganites in superlattices using a two-orbital double-exchange model including superexchange interactions, Jahn-Teller lattice distortions, and long-range Coulomb interactions. The magnetic and transport properties critically depend on the thickness of the AF...

Structural and electronic properties of germanene/MoS2 monolayer and silicene/MoS2 monolayer superlattices

Superlattice provides a new approach to enrich the class of materials with novel properties. Here, we report the structural and electronic properties of superlattices made with alternate stacking of two-dimensional hexagonal germanene (or silicene) and a MoS2 monolayer using the first principles approach. The results are compared with those of graphene/MoS2 superlattice. The distortions of the ...
