Motivation and plan

  • Two major detection mechanisms in graphene radiation sensors: (photo)thermoelectric- and plasma (Dyakonov-Shur, DS) mechanisms.
  • The same functional form – it is difficult to tell the mechanisms apart in the common geometries.
  • One goal is to use unusual device layouts, which favor only one mechanism at a time.
  • More clues from the THz ratchet effects and detection measurements in the magnetic field.
  • An eye on practical detectors; may be even realize a constructive action of the both mechanisms.

Data creation

epub.uni-regensburg.de; switch to English and write “FLAG-ERA” or “DeMeGRaS” in the search field​.
Samples data from Chalmers: https://doi.org/10.5281/zenodo.6412577

Outreach and other activities:

  • Travel grant of VW Stiftung supporting cooperation of German and Ukraine scientists
  • Regensburg: 2 PhD’s with great honour (S. Hubmann, M. Otteneder) plus one PhD with very good note (S. Candussio); Seminars; No exchange and travelling due to the pandemic.
  • Montpellier hired Ukrainian engineer to help the French research team and to develop his skills with novel and unique THz experimental setups in the frame of DeMeGras, and MUSE action of Montpellier University allows him to keep his job waiting for his next position.
  • Web page of the project: https://www.chalmers.se/en/departments/mc2/research/quantum-device-physics/demegras/
    The inconvenience with having a long name of the homepage is compensated by the free support offered by Chalmers IT service.
  • Graphene radiation detectors were included in the course Graphene science and technology (MCC130) of the Master’s program Nanotechnology (Chalmers University of Technology)
