Atomistic simulations may enable predictive analysis of nanoelectronic devices for which direct experimental investigation could often be extremely challenging and prohibitively expensive. In this talk, I shall discuss electronic device modeling and simulation using the non-equilibrium Green's function (NEGF) method, which is regarded as one of the most rigorous quantum transport formalisms within single electron approximation. Specifically, I shall focus on electronic devices based on two-dimensional layered materials, such as graphene and molybdenum disulfide (MoS₂), which have recently received significant attention due to their unique physical properties and potential for use in future electronics. I shall describe how quantum confinement, electron-phonon scattering and non-idealities such as edge roughness could affect device performance in these material systems. Taking these effects into account in a self-consistent manner is making it increasingly possible to simulate realistic device performance starting from every atom. I shall conclude with an outlook on the future of layered material electronics.
