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

Low-toxicity, air-stable cesium bismuth iodide Cs(3)Bi(2)X(9) (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 constants, band structures, density of states, and optical prop...
