Novel phase transition for XSnN2 (X = Mg, Zn) under uniaxial compression

Kai Chen et al.

Summary: The behavior of ternary nitrides MgSnN2 and ZnSnN2 under compression was computationally explored. Phase transitions were observed for both materials at certain pressures, and the structural recovery differed after compression release. In addition, the band gap of MgSnN2 increased with compression, while the band gap of ZnSnN2 decreased. Light absorption was suppressed under compression but enhanced at high frequencies. The metastable structure of MgSnN2 showed promising conductive properties.

Investigation of double perovskites Sr2SmNbO6 and X2CoNbO6 (X1/4Sr,Ba) with SCAN functional and plus U correction

Ying Zeng et al.

Summary: The double perovskites Sr2SmNbO6, Sr2CoNbO6, and Ba2CoNbO6 were investigated using first principles computations based on density functional theory and plus U treatment. The study found that PBE + U or SCAN + U methods were effective in explaining the semiconducting nature of these materials, providing a useful guide for future research.

First principles investigation of electron correlation and Lifshitz transition within iron polynitrides

Qingguo Feng

Summary: In this work, electron correlations within iron poly-nitrogen compounds were investigated as a function of nitrogen concentration and pressure. The Coulomb interaction strengths decreased monotonically with increasing nitrogen concentration, while electrons became more delocalized as pressure increased. A unique electronic topological transition was found for FeN2, with a breaking of spin symmetry and transition of magnetism induced by a structural change. Additionally, band structure, densities of states, Fermi surface, and absorption spectra were calculated and discussed.

The pressure effect on the structural, elastic, and mechanical properties of orthorhombic MgSiN2 from first-principles calculations

Atipong Bootchanont et al.

Summary: In this study, first-principles calculations were used to investigate the pressure effects on the structural and mechanical properties of orthorhombic MgSiN2. The results showed that the material remained mechanically stable under pressures up to 10 GPa, with the elastic moduli, Poisson's ratio, and hardness increasing with pressure.

Band Gap-Tunable (Mg, Zn)SnN2 Earth-Abundant Alloys with a Wurtzite Structure

Naoomi Yamada et al.

Summary: Wurtzite-type MgxZn1-xSnN2 alloys are proposed as promising earth-abundant and tunable band gap semiconductors with the potential to be grown on GaN substrates. These alloys show green-light emissions and can be tuned from 1.5 to 2.3 eV by increasing the composition parameter x. Direct-gap semiconductors with band gaps in the range of 1.8 to 2.5 eV are highly anticipated for the development of green LEDs and high-efficiency tandem solar cells.
