Abstract

Graphene is a two-dimensional crystal consisting of a monatomic layer of carbon atoms. Electrons and holes in graphene behave as quasi-relativistic particles with zero effective mass and large (as compared to semiconductors) Fermi velocity. These unique physical properties can be used for designing detectors, emitters and modulators of terahertz radiation. Here we discuss several ideas of using graphene based structures for emission of terahertz radiation.
