Across my career, I have followed and steered this process in real time: first for organic semiconductor films for photovoltaics, linking growth and molecular packing to excitonic and charge-transfer properties, and then for 2D and wide-bandgap crystals. I will show how coupling growth with in situ probes and data-driven analysis turns trial-and-error synthesis into controlled epitaxy of graphene, hexagonal boron nitride (hBN), and beyond. I will close with perspectives for future work: hBN as an integration platform for device-grade van der Waals heterostructures, with in situ growth control as the engine.<\/p>\n<\/div><\/section>","protected":false},"excerpt":{"rendered":"","protected":false},"author":2,"featured_media":73855,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3,8],"tags":[],"class_list":["post-78608","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-a-la-une","category-actualites"],"_links":{"self":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/78608","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\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/comments?post=78608"}],"version-history":[{"count":3,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/78608\/revisions"}],"predecessor-version":[{"id":78610,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/78608\/revisions\/78610"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/media\/73855"}],"wp:attachment":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/media?parent=78608"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/categories?post=78608"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/tags?post=78608"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
