Electrically Tunable Nonlinearity at 3.2 Terahertz in Single-Layer Graphene
{{output}}
Graphene is a nonlinear material in the terahertz (THz) frequency range, with χ(3) ∼ 10-9 m2/V2 ∼ 15 orders of magnitude higher than that of other materials used in the THz range, such as GaAs or lithium niobate. This nonlinear behavior, combined with ultra... ...
