Abstract :
A new type of continuous-wave (CW) terahertz (THz) emitter was fabricated using multilayer graphene (MLG) electrodes on LTG-GaAs photomixer instead of metal electrodes. Unique graphene properties allow high optical power illumination for high photocurrent generation and show the potential for reliable CW THz emission.
