Cuprate-like electronic properties in superlattices with Ag(II)F₂ square sheet
1Institute of Advanced Studies, Nanyang Technological University, 50 Nanyang Avenue, 639798 Singapore.
Abstract:
Using the generalized gradient approximation augmented with maximally localized Wannier functions analysis, we present the formation of cuprate-like electronic structures in Ag(II)F2-related superlattices resulted from the confinement together with structural chemical modification. The out-of-plane electronic reconstruction leads to electron doping of AgF2 plane and gradually destablizes the antiferromagnetic state. Eventually a stable nonmagnetic metallic state emerges by applying in-plane tensile strain, in which the shape of effective Fermi surface of AgF2 plane exhibits the key feature of high-temperature cuprate superconductor.

02:46Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than...

Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
02:58Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.

03:02Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
