Plasmonic Terahertz Nonlinearity in Graphene Disks. Issue 2 (2nd February 2022) - Han, Jeong Woo
Abstract : Plasmonic Nonlinearity In article number 2100218, Martin Mittendorff and co‐workers investigate the origin of nonlinear terahertz absorption in micrometer‐sized graphene disks. Exploiting polarization sensitive pumpprobe measurements, thermal and nonthermal contributions are disentangled. When illuminated resonantly with circularly polarized radiation, the electrons start to move in circular trajectories, inducing a magnetic field perpendicular to the surface of the disks.
