抄録

We report on amplified spontaneous broadband terahertz emission in 1-7.6 THz range at 100 K via current injection in a distributed-feedback (DFB) dual-gate graphene-channel transistor. The device exhibited a nonlinear threshold-like behavior with respect to the currentinjection level. A precise DFB cavity design is expected to transcend the observed spontaneous broadband emission to single-mode THz lasing.
