All-graphene terahertz analog nanodevices and nanocircuits

In this talk, we present the concept of terahertz (THz) nanocircuit devices realized with multiple-terminal, integrally-gated graphene plasmonic channels. To develop an all-graphene THz transmitter front-end, we propose the design of its key constituting components in grapheme, including graphene-based interconnects, oscillators, multipliers, phase shifters, filters, matching networks and on-chip antennas, of which high degree of tunability and switchability are enabled by the electronic doping of graphene monolayer. This all-graphene THz circuit module presents a fundamental step towards post-silicon solutions for innovative THz communication, sensing and actuation systems.
