Dimension-Dependent Bandgap Narrowing and Metallization in Lead-Free Halide Perovskite Cs<sub>3</sub>Bi<sub>2</sub>X<sub>9</sub> (X = I, Br, and Cl) under High Pressure

Dimension-Dependent Bandgap Narrowing and Metallization in Lead-Free Halide Perovskite Cs<sub>3</sub>Bi<sub>2</sub>X<sub>9</sub> (X = I, Br, and Cl) under High Pressure

Low-toxicity, air-stable cesium bismuth iodide Cs<sub>3</sub>Bi<sub>2</sub>X<sub>9</sub> (X = I, Br, and Cl) perovskites are gaining substantial attention owing to their excellent potential in photoelectric and photovoltaic applications. In this work, the lattice...
