Outline of Final Research Achievements |
In this study, for the realization of room-temperature operating terahertz plasmonic devices utilizing graphene plasmons, we theoretically verified device operation principles of plasmonic devices such as plasmon instabilities in asymmetric dual-grating-gate graphene transistors, interband population inversion in monolayer graphene, and resonant tunneling in double graphene layer. Especially, in the asymmetric dual-grating-gate graphene transistors, we demonstrated that a giant plasmon instability can take place due to the simultaneous occurrence of the so-called Dyakonov-Shur instability and Ryzhii-Satou-Shur instability.
