Room temperature broadband terahertz gains in graphene heterostructures based on inter-layer radiative transitions
We exploit inter-layer radiative transitions to provide gains to amplify terahertz waves in graphene heterostructures. This is achieved by properly doping graphene sheets and aligning their energy bands so that the processes of stimulated emissions can overwhelm absorptions. We derive a...
