In this work, we show that a hydrodynamic instability can be ex\u00acplored (the Dyakonov\u2013Shur instability) to excite the graphene plasmons. The instability can be sustained with the help of a source-to-drain current and con\u00actrolled with the gate voltage. It is shown that the plasmons radiate a frequency comb in the Terahertz (THz) range. It is argued how this can pave the stage for a new generation of low power THz sources in integrated-circuit technology.<\/p>\n\n\n\n<p><em>\u00a9 The Authors, published by EDP Sciences, 2020<\/em><\/p>\n\n\n\n<figure class=\"wp-block-embed\"><div class=\"wp-block-embed__wrapper\">\nhttps:\/\/www.epj-conferences.org\/articles\/epjconf\/abs\/2020\/09\/epjconf_cmpnc2019_03006\/epjconf_cmpnc2019_03006.html\n<\/div><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>EPJ Web of Conferences&nbsp;233, 03006 (2020)https:\/\/doi.org\/10.1051\/epjconf\/202023303006 Pedro Cosme1,2* 1&nbsp;Instituto de Plasmas e Fus\u00e3o Nuclear, 1049-001 Lisboa, Portugal&nbsp;2&nbsp;Instituto Superior T\u00e9cnico, 1049-001 Lisboa, Portugal&nbsp; *&nbsp;Corresponding author:&nbsp;pedro.cosme.e.silva@tecnico.ulisboa.pt Published online:&nbsp;16 April 2020 Abstract Graphene Field-effect transistors (GFETs) are excellent candidates for all-electric, low-power radiation sources and detectors based on integrated circuit technology.
