Summary
Chemical short-range order (SRO) in multi-principal element materials influences electronic properties. This study reveals SRO
Area of Science:
- Materials Science
- Condensed Matter Physics
- Computational Materials Science
Background:
- Chemical short-range order (SRO) is a key structural feature in multi-principal element materials.
- Its impact on site-resolved properties like magnetic moments and d-band centers is not well understood.
- Understanding SRO is crucial for tuning material functionalities.
Purpose of the Study:
- To investigate the origin and influence of chemical short-range order (SRO) in 2D ternary transition metal dichalcogenides (TMDCs).
- To establish the relationship between SRO and site-resolved electronic and magnetic properties.
- To identify descriptors for SRO formation and regimes of SRO influence.
Main Methods:
- High-throughput first-principles calculations.
- Machine learning models for descriptor identification.
- Analysis of atomic arrangements and site-resolved properties.
Main Results:
- Chemical affinity and atomic size difference are identified as dominant SRO descriptors.
- Weak SRO in (V0.5Cr0.5)S2 minimally affects half-metallicity but modulates site-resolved magnetic moments and d-band centers.
- Strong SRO in (Re0.5Ta0.5)S2 suppresses mid-gap states, leading to a semiconducting band gap.
- The MACE-MP descriptor accurately maps local atomic arrangements to site-resolved properties.
Conclusions:
- Chemical short-range order is a fundamental parameter for designing multi-scale material functionalities.
- SRO significantly influences site-resolved properties even when global electronic properties remain largely unchanged.
- The findings provide insights into controlling electronic and magnetic behavior in complex materials through SRO engineering.

Crystal Field Theory
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.

Tetrahedral 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...

Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and...

02:58Properties of Transition Metals
31.2K
Transition metals are defined as those elements that have partially filled d orbitals. As shown in Figure 1, the d-block elements in groups 3–12 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals.

Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

Color in Coordination Complexes
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...
