Article Synopsis
  • The study investigates the structural, elastic, electrical, optical, and thermoelectric properties of oxide-based BaAsBO materials (specifically with Nb and Ta) using first-principles calculations via the WIEN2k code.
  • The research identifies a direct band gap of 1.97 eV for BaAsNbO and 1.49 eV for BaAsTaO, confirming their semiconducting nature, and shows that BaAsNbO has a promising spectroscopic limited maximum efficiency (SLME) of 32% for use in solar cells.
  • Finally, transport properties reveal favorable zT values (0.757 for BaAsNbO and 0.751 for BaAs

In this study, we employed density functional theory coupled with the full-potential linearized augmented plane-wave method (FP-LAPW) to investigate the structural, electronic, and magnetic properties of the TiFeAs alloy adopting the HgCuTi-type structure. Our findings demonstrate that all the examined structures exhibit ferromagnetic (FM) behaviour. By conducting electronic band structure calculations, we observed an energy gap of 0.

In this study, the density functional theory (DFT) was employed to study the structural, electronic, optical, and thermoelectric characteristics of half-Heusler (HH) FeTaX (X = P or As). Optimization of the structures was achieved using Perdew-Burke-Ernzerhof (PBE) parametrized generalized gradient approximation (GGA). These HH FeTaX (X = P, As) showed indirect bandgaps of 0.

This work presents the investigation of physical characteristics including structural, electronic, elastic, optical and thermoelectric, of the double perovskite (DP) oxide SrScBiO with the aid of the FP-LAPW method, dependent on DFT combined with BoltzTraP code. To incorporate the inclusion of exchange as well as correlation effects, approximations like LDA and three different forms of GGA [PBE-GGA, WC-GGA & PBEsol-GGA] are applied. The mBJ-GGA method including spin-orbital coupling (SOC) & not including SOC was utilised in this investigation and it was carried out in the WIEN2k code.

The main goal of modern manufacturing is to create products that are affordable, eco-friendly, and energy-efficient. With a focus on HgCrO, this study sought to discover molecules that meet these requirements. The structural, electrical, thermodynamic, and transport properties of the material were investigated using Wien2K, a full-potential, linearized augmented plane wave program (FP LAPW).
