Negative Terahertz Conductivity in Remotely Doped Graphene Bilayer Heterostructures *
This chapter demonstrates that remote doping enhances the indirect interband generation of photons in the proposed graphene bilayer (GBL) heterostructures. It deals with the GBL heterostructures with a remote impurity layer (RIL) located at some distance from the GBL plane, and incorporating donors and acceptors or donor and acceptor clusters. …
