Electronic properties of Pb-I deficient lead halide perovskites

Chao Zheng, Oleg Rubel, Mikaël Kepenekian +2

The electronic structure evolution of deficient halide perovskites with a general formula $(A,A^{\prime }{)}_{1+x}{M}_{1-x}{X}_{3-x}$ was investigated using the density functional theory. The foc…
