摘要

The halide perovskite CsPbBr3 demonstrates great potential for use in various optoelectronic devices due to its exceptional photoelectric properties. However, electron mobility in these crystals remains insufficiently high. Experimental studies of the crystal structure and electronic properties of CsPb(Br1 – xClx)3 single crystals have allowed for the determination of an optimal impurity chlorine ion content ( \(x \approx 0.07\) ), which significantly increases electron mobility to a value of 215.2 cm2 V–1 s–1.
