DFT-driven insights into (Sr/Ba)2GaBiO6 double perovskites for next-generation optoelectronic and thermoelectric technologies

AI Insight

This study employs Density Functional Theory (DFT) computational methods to investigate the structural, electronic, and transport properties of Sr2GaBiO6 and Ba2GaBiO6 double perovskite compounds. The calculations examine key parameters including band gap characteristics, optical absorption spectra, and thermoelectric coefficients such as the Seebeck coefficient, electrical conductivity, and thermal conductivity. The results suggest these materials possess properties potentially suitable for optoelectronic applications and thermoelectric energy conversion.

Why it matters

Double perovskites with tunable band gaps and favorable thermoelectric figures of merit could contribute to the development of more efficient solar cells, photodetectors, and waste-heat recovery devices, reducing dependence on fossil fuels and improving energy efficiency across multiple technology sectors.
