Indirect-to-direct band gap transition and optical properties of Cs2BiAgX6 with mechanical strains: the density functional theory investigation
The last research of Cs2BiAgX6 (X = Cl, Br) exhibiting a desired band gap in the visible imply that the compounds maybe as a potential candidate for CH3NH3PbI3. However, both the band gaps of Cs2BiAgCl6 and Cs2BiAgBr6 are indirect, which means the optical properties will be limit. Hence, it is a cri...
