Overview

Investigating barium doping's effects on optical and electronic properties in SrH2, suggesting improved performance for energy storage.

Key Points

  • This research aims to analyze how barium doping affects the structural and optoelectronic properties of SrH₂.
  • Utilized density functional theory (DFT) for analysis.
  • Compared structural and electronic properties of pristine and Ba-doped SrH₂.
  • Assessed changes in optical properties such as absorption coefficient and refractive index.
  • Band gap increased from 1.3 eV in pristine SrH₂ to 1.7 eV with Ba doping.
  • Enhanced optical response noted, with improved reflectivity and conductivity.
  • Modified dielectric function components indicate better charge carrier mobility.
