Scientists Spin Graphene and Gold into Terahertz Waves
DRESDEN, Germany, Dec. 29, 2020 — A German-Spanish research team has developed a graphene-based approach for increasing the efficiency with which the scientists were able generate terahertz pulses. In the system, the researchers coated a graphene sheet with a metallic lamellar structure — specifically, gold lamellae. As scientists currently rely on complex accelerator devices and/or large lasers to generate terahertz waves, the capabilities of the new material system, and possibly the material itself, make it
