Abstract:Two-dimensional materials and their multilayers or heterostructures are promising candidates for optoelectronic devices. Their performance such as the transient current can be remarkably modified under irradiation since the atoms are extremely exposed. This effect, however, still lacks theoretical understanding. Using real-time time-dependent density functional theory extended to open systems for electrons and Ehrenfest dynamics for the moving ion, we explore the single-ion irradiation effects on graphene elec… Show more
