The group has expertise in the development of porous materials based on binary transition metal nitride (VN, W<sub>2<\/sub>N, Mo<sub>2<\/sub>N, RuN, TiN, NbN, etc.) acting as electrodes for micro-supercapacitors. To increase storage performance, one approach we have chosen is to develop multi-cationic thin films (ternary, quaternary and quinary transition nitride) by magnetron sputtering in planar or confocal mode. In order to obtain an electrode in which 2 cations are electroactive, we will alternate nanometric layers of binary thin films ('nanolaminate' approach) in which we will co-sputter the two metals simultaneously under Ar\/N<em><sub>2<\/sub><\/em>\/O<em><sub>2<\/sub><\/em>. The confocal mode approach makes it possible to implement a combinatorial approach that can scan a large number of different compositions\/phases. To achieve this optimisation, we will be using a sputtering frame with several confocal sources, which will enable us to obtain a chemical composition gradient on a complete 4-inch wafer. Using multi-technique mapping tools (structural, chemical, mechanical, electrical, electrochemical, etc.), we will be able to trace the composition and structure of the deposit at wafer scale.<\/p>\n<table width=\"628\">\n<tbody>\n<tr>\n<td width=\"628\"><a href=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/06\/NRJ2.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-65783 aligncenter\" src=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/06\/NRJ2-300x53.jpg\" alt=\"\" width=\"500\" height=\"89\" srcset=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/06\/NRJ2-300x53.jpg 300w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/06\/NRJ2-18x3.jpg 18w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/06\/NRJ2.jpg 612w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/a><\/td>\n<\/tr>\n<tr>\n<td width=\"628\"><em>\u00a0Illustration of deposition possibilities by alternating layers of varying thickness, either alternately (nano-laminate) or simultaneously. <strong>B)<\/strong> X-ray micro-fluorescence mapping showing a composition gradient.<\/em><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div><\/div><\/div><\/section>\n<section class='av_toggle_section av-lxeocee7-341966e411fe37f720d60563f7e6f653'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div role=\"tablist\" class=\"single_toggle\" data-tags=\"{All} \"  ><p id='toggle-toggle-id-2' data-fake-id='#toggle-id-2' class='toggler  av-title-above'  itemprop=\"headline\"  role='tab' tabindex='0' aria-controls='toggle-id-2' data-slide-speed=\"200\" data-title=\"Micro super-capacit\u00e9s\" data-title-open=\"\" data-aria_collapsed=\"Click to expand: Micro super-capacit\u00e9s\" data-aria_expanded=\"Click to collapse: Micro super-capacit\u00e9s\">Micro super-capacitors<span class=\"toggle_icon\"><span class=\"vert_icon\"><\/span><span class=\"hor_icon\"><\/span><\/span><\/p><div id='toggle-id-2' aria-labelledby='toggle-toggle-id-2' role='region' class='toggle_wrap  av-title-above'  ><div class='toggle_content invers-color'  itemprop=\"text\" ><\/div><\/div><\/div><\/section>\n<\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":2,"featured_media":0,"parent":16390,"menu_order":10,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-16815","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/pages\/16815","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/comments?post=16815"}],"version-history":[{"count":0,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/pages\/16815\/revisions"}],"up":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/pages\/16390"}],"wp:attachment":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/media?parent=16815"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
