Two-dimensional (2D) materials are emerging as key candidates for next-generation electronic devices. To assess their application potential, it's crucial to accurately determine their carrier mobility, which is governed by electron-phonon scattering processes. Our research utilizes density functional theory (DFT) calculations to determine carrier mobility in several 2D Janus materials, taking into account various phonon scattering mechanisms. We have successfully identified the dominant scattering mechanisms that significantly impact mobility, thereby shedding light on the electronic transport characteristics of these materials.
