Strain Induced Topological Insulator Phase in CsPbBr<i><sub>x</sub></i>I<sub>3−<i>x</i></sub> (<i>x</i> = 0, 1, 2, and 3) Perovskite: A Theoretical Study

Strain Induced Topological Insulator Phase in CsPbBr<i><sub>x</sub></i>I<sub>3−<i>x</i></sub> (<i>x</i> = 0, 1, 2, and 3) Perovskite: A Theoretical Study

First-principles density functional theory was used to determine the surface band structures of CsPbBr<i><sub>x</sub></i>I<sub>3−<i>x</i></sub> (<i>x</i> = 0, 1, 2, and 3) perovskites. The equilibrium lattice constants of CsPbBr<i><...
