Variations in lattice (κ_l), electronic (κ_e) and total thermal conductivity (κ_t) against selected range of temperature for Cs₂MGaBr₆ halide perovskites. [Lattice thermal conductivity (κ_l) has been computed using the Gibbs2 code, while electronic thermal conductivity (κ_e) was calculated via the BoltzTraP code].
