Overview

Density functional theory correlates halide substitution with electronic and thermoelectric properties in Rb₂InGeX₆ perovskites, indicating strong potential for optoelectronic applications.

Key Points

  • Rb₂InGeCl₆ shows strong UV absorption, making it suitable for UV photodetectors and light-harvesting technologies.
  • Rb₂InGeBr₆ demonstrates n-type conduction with an enhanced Seebeck coefficient, implying superior thermoelectric performance.
  • Investigations reveal that optical properties vary significantly with halide substitution, influencing light-matter interactions.
  • Significant tunability of the electronic and thermodynamic properties of Rb₂InGeX₆ supports advancements in energy harvesting applications.
