Key Points

Modification of the band gap occurs through aliovalent anion substitution, enhancing material design.
Using SrBi3O4Cl3 and Bi4O4SeCl2, the study shows significant changes in properties due to substitutions.
Assessment through electronic structure analysis reveals how the atomic arrangement affects band gaps.
Implications for material engineering arise from understanding substitution effects on band structure.

Implication

Chemical substitution alters the band gap and atomic structure in materials, indicating new property designs.

Abstract

Modifying the atomic and electronic structure of materials by chemical substitution is a common method of achieving properties by design. Cations and metal atoms are the most frequent choices for...
