In this paper, we describe a first-principles full-band Monte-Carlo method that utilizes full scattering matrix-elements while retaining the benefits of the analytical approach. We apply this method to the study of field-dependent electron transport in monolayer WS2. To show the limits of applicability, we compare our approach to a simplified effective mass method. For the effective mass method, we extract inter- and intra-valley deformation potentials to match closely the scattering rates of the full-band approach.engProceedings paper10.1109/sispad66650.2025.11185915WOS:001846246700004
