| Abstract
|
| The excellent performance of metal halide perovskite CsPbBr3 as a light emitter has attracted many researchers to consider it as a potential material for next-generation lighting, displays, and quantum information applications. However, its crucial drift mobility is limited by phonon scattering. In this paper, we use first-principles calculations to obtain the electronic-phonon coupling properties of CsPbBr3, including polar optical phonons, and then use the linear Boltzmann equation to obtain the drift mobility under an electric field. This paper also presents a detailed study of the anisotropic charge carrier transport properties of CsPbBr3, providing essential information for the application of metal halide perovskites. |
