Research paperExperimental CharacterizationTheoreticalElectrical tunability of terahertz nonlinearity in grapheneSergey Kovalev, Hassan A. Hafez, Klaas-Jan Tielrooij, Jan-Christoph Deinert et al.2026·10.1126/sciadv.abf9809·arXiv:2604.24651AbstractGraphene's terahertz nonlinearity can be efficiently tuned by electrical gating. The paper demonstrates gate-controlled saturable absorption and higher-harmonic generation in graphene at room temperature under ambient conditions, and compares the results with a physical model of carrier heating and cooling under ultrafast THz excitation.Read more
