Experimental realization of two-dimensional Dirac nodal line fermions in monolayer Cu2Si

Nodal line semimetals have been observed in three-dimensional materials but are missing in two-dimensional counterparts. Here, Feng et al. report two-dimensional Dirac nodal line fermions protected by mirror reflection symmetry in monolayer Cu2Si.
