DESCRIPTION:Speakers: Aleksandra Krajewska (CENTERA Laboratories\, Institu
 te of High Pressure Physics PAS\, Warsaw\, Poland)\nTerahertz (THz) system
 s and technology have become of large interest over the last 20 years. How
 ever\, it still needs new and innovative solutions in the field of both ge
 neration and detection of THz radiation. Despite the fact that scientists 
 in many research centers are constantly working on the production of new T
 Hz sources and detectors based on semiconductors such as silicon\, it turn
  out that carbon nanomaterials\, including graphene and van der Waals hete
 rostructures consisting of layered two-dimensional (2D) materials (h-BN or
  MoS2) are extremely promising materials for amplification and emission of
  THz radiation. Also\, combination of 2D materials with “classical” se
 miconductor materials like GaN and/or GaAs can lead to the production of m
 aterials with unprecedented THz properties.\nWe demonstrate different meth
 ods of  manufacturing nanodevices based on graphene and other 2D related m
 aterials. These methods include both the fabrication of 2D heterostructure
 s from the micrometer scale to large surface area materials. We present st
 ep-by-step how to combine 2D materials with different materials\, e.g. sem
 iconductors\, and how to fabricate matrices of THz elements (detectors\, m
 etasurfaces). \nA comprehensive characterization of the basic electric and
  THz properties of these materials will be also presented. Preliminary res
 ults and theoretical analysis indicate the great potential of graphene-bas
 ed nanostructures for terahertz applications.\n\n**Acknowledgements**\nThe
