\u00e0 la r\u00e9volution digitale en cours et l\u2019importance dans notre vie de tous les jours de l\u2019internet des objets, a entrain\u00e9 le d\u00e9veloppement de nombreux syst\u00e8mes de communications sans fils. De nouveaux syst\u00e8mes sont envisag\u00e9s dans des gammes de fr\u00e9quence peu utilis\u00e9es jusqu\u2019\u00e0 pr\u00e9sent, telles que les bandes de fr\u00e9quence au-del\u00e0 de 100GHz. Ces bandes de fr\u00e9quence peuvent supporter des d\u00e9bits importants. Pour ces syst\u00e8mes, il est n\u00e9cessaire de proposer des commutateurs haute fr\u00e9quence qui puissent router les signaux de mani\u00e8re efficace \u00e0 ces fr\u00e9quences.<br \/>\nDans cette th\u00e8se, nous proposons de d\u00e9velopper des commutateurs RF fonctionnant \u00e0 tr\u00e8s haute fr\u00e9quence (&gt;100GHz) et fabriqu\u00e9s \u00e0 partir de mat\u00e9riaux qui ont \u00e9merg\u00e9s ces derni\u00e8res ann\u00e9es : les mat\u00e9riaux 2D. Ces commutateurs sont constitu\u00e9s d\u2019une \u00e0 quelques monocouches de mat\u00e9riau 2D, ins\u00e9r\u00e9es entre deux \u00e9lectrodes m\u00e9talliques.<br \/>\nCe travail de th\u00e8se a \u00e9t\u00e9 financ\u00e9 par le projet ANR SWIT n\u00b0 ANR-19-CE24-0004-01, sous la coordination du Dr. Emiliano PALLECCHI, et en partenariat avec le CEA LETI, IMEP-LaHC. Les composants ont \u00e9t\u00e9 con\u00e7us et fabriqu\u00e9s en utilisant du disulfure de molybd\u00e8ne (MoS2) avec 3 et 6 monocouches atomiques dont la croissance est faite au LETI. Compte tenu du mode de fonctionnement de ces composants, la commutation s\u2019effectue en appliquant une rampe en tension positive ou n\u00e9gative pour le faire commuter. Diff\u00e9rentes combinaisons de m\u00e9taux ont \u00e9t\u00e9 explor\u00e9es. Ces commutateurs s\u2019ins\u00e8rent facilement dans les structures de propagation de type coplanaire. La caract\u00e9risation de ces composants jusqu\u2019\u00e0 67GHz a permis d\u2019obtenir des pertes d\u2019insertion autour de -1dB (dispositif \u00e0 l\u2019\u00e9tat ON) et une isolation de -25dB (dispositif \u00e0 l\u2019\u00e9tat OFF) \u00e0 67GHz.

New systems are being considered in frequency ranges that have been little used until now, such as frequency bands above 100GHz. These frequency bands can support high data rates. For these systems, it is necessary to propose high frequency switches that can route signals efficiently at these frequencies.<br \/>\nIn this thesis, we propose to develop RF switches operating at very high frequencies (&gt;100GHz) and made from materials that have emerged in recent years: 2D materials. These switches are made of one to a few monolayers of 2D material, inserted between two metallic electrodes.<br \/>\nThis thesis work was funded by the ANR SWIT project n\u00b0 ANR-19-CE24-0004-01, under the coordination of Dr. Emiliano PALLECCHI, and in partnership with CEA LETI, IMEP-LaHC. The components have been designed and fabricated using molybdenum disulfide (MoS2) with 3 and 6 atomic monolayers grown at LETI. Given the mode of operation of these components, switching is done by applying a positive or negative voltage ramp to make it switch. Different combinations of metals have been explored. These switches are easily inserted in coplanar propagation structures. The characterization of these components up to 67GHz has resulted in insertion losses around -1dB (device in ON state) and isolation of -25dB (device in OFF state) at 67GHz. The characterization and analysis of the non-linear properties of these switches (IP3 of the order of 35 dBm) has been performed. This allowed us to develop a simulation model under ADS\u00ae, which relies on the I-V characteristics to predict their nonlinear behavior.<br \/>\nA collaboration on this topic was conducted with the University of Texas at Austin. In this context, switches with an atomic monolayer have been fabricated (U. Texas-Austin) and characterized at the IEMN.<br \/>\nIn a first phase, switches based on a boron nitride (hBN) monolayer have been studied. These devices have been characterized up to 220 GHz, and the performances of this type of switch have been validated by successfully integrating them in a high speed transmission system with a carrier at 100GHz (On Off Keying (OOK) modulation with a data rate of 8.5 Gbits.s-1).<br \/>\nIn a second phase, the optimization of propagation structures, coupled with the fabrication of switches based on a MoS2 monolayer, allowed us to validate the behavior of the switches for signals up to 500GHz. We were thus able to show that these switches met the IEEE standard for the future 6G telecommunications standard. Indeed, considering a carrier at 320 GHz, different modulation schemes were tested and we reached a maximum data rate of 100GBit.s1 for a quadrature amplitude modulation (QAM 16). A demonstrator with a real time video stream integrating these switches has been tested and validated successfully.<\/p>\n<\/div><\/section>","protected":false},"excerpt":{"rendered":"","protected":false},"author":20,"featured_media":56845,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[8,87,65,84,318],"tags":[],"class_list":["post-56841","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-actualites","category-agenda-en","category-agenda","category-agenda-en-en","category-these-2023"],"_links":{"self":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/56841","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/users\/20"}],"replies":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/comments?post=56841"}],"version-history":[{"count":0,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/56841\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/media\/56845"}],"wp:attachment":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/media?parent=56841"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/categories?post=56841"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/tags?post=56841"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
