"new class of terahertz devices... etching metastructure patterned contacts at sub-wavelength distances onto gallium nitride and indium gallium nitride semiconductor... allow control of electrical fields inside device significantly boosting performance without relying on aggressive downscaling... can reach 20 THz. and support over 20 V. enabling transmission and modulation of THz signals with much greater power and frequency... compatible with existing manufacturing... data transmission 100 Gbps at THz frequencies"
