Abstract

This paper reviews recent advances in the research and development of graphene-layer (GL) based van der Waals (vdW) two-dimensional (2D) heterostructures for fast, sensitive terahertz (THz) detection. 2D plasmonic nonlinearity as well as photothermoelectric effects in GL and other Dirac semimetals/semiconductors are promising mechanisms for highly sensitive, fast-response, room-temperature THz detection. The vertical GL and b-AsxP1-x heterostructures enable a new ultrafast bolometric mechanism enhancing the GL-based THz photodetector performance. We also introduce our recently developed GL- and other Dirac-semimetal/semiconductor-based rectenna FET structures, supporting a so-called 3D rectification mechanism. This mechanism supports fast and highly sensitive zero-power consumption extremely low-noise THz detection, which was experimentally verified, with further experiments in progress.
