By exploiting the electric field concentration at the graphene\/electrolyte interface, a modulation as high as 45% is achieved in a wide spectral range (1.5-6 THz) with applied voltages in the range [-0.6 V, +0.6 V], which is remarkable considering the small voltages and the atomically thin active region. Graphene-based THz modulators&#8217; main advantages are: facile fabrication, low cost and excellent tunability, thus promising for THz system applications.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Sarfraz S.M.A.; Di Gaspare A.; Di Franco C.; Ligonzo T.; Ambrico M.; Vitiello M.S.; Scamarcio G.<\/p>\n","protected":false},"featured_media":1294,"comment_status":"closed","ping_status":"open","template":"","meta":[],"product_cat":[709],"product_tag":[3335],"class_list":["post-9089","product","type-product","status-publish","has-post-thumbnail","hentry","product_cat-proceedings-papers","product_tag-electrolyte-gated-graphene","prodpage-style2"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product\/9089","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/comments?post=9089"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/media\/1294"}],"wp:attachment":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/media?parent=9089"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product_cat?post=9089"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product_tag?post=9089"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
