Twist-angle between component layers has emerged as a remarkable parameter that can control the period of lateral confinement, and nature of the exciton (Coulomb bound electron-hole pair) in reciprocal space thus creating exotic physical states including moir\u00e9 excitons. In this review article, we focus on opto-electronic properties of excitons in twisted 2D transition metal dichalcogenide (TMD) semiconductor BL-HS. We look at existing evidence of moir\u00e9 excitons in localized and strongly correlated states, and at nanoscale mapping of moir\u00e9 superlattice and lattice-reconstruction. This review will be helpful in guiding the community as well as motivating work in areas such as near-field optical measurements and controlling the creation of novel physical states.<\/p>\n<p>Paper available at: https:\/\/arxiv.org\/abs\/2008.07086<\/p>\n<p>&nbsp;<\/p>\n<\/div>\n\t\t<\/div><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>Fabricating van der Waals (vdW) bilayer heterostructures (BL-HS) by stacking the same or different two-dimensional (2D) layers, offers a unique [&hellip;]<\/p>\n","protected":false},"author":3,"featured_media":495,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[],"class_list":["post-486","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-new-papers"],"_links":{"self":[{"href":"https:\/\/physics.iisc.ac.in\/~aksy\/wp-json\/wp\/v2\/posts\/486"}],"collection":[{"href":"https:\/\/physics.iisc.ac.in\/~aksy\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/physics.iisc.ac.in\/~aksy\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/physics.iisc.ac.in\/~aksy\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/physics.iisc.ac.in\/~aksy\/wp-json\/wp\/v2\/comments?post=486"}],"version-history":[{"count":3,"href":"https:\/\/physics.iisc.ac.in\/~aksy\/wp-json\/wp\/v2\/posts\/486\/revisions"}],"predecessor-version":[{"id":490,"href":"https:\/\/physics.iisc.ac.in\/~aksy\/wp-json\/wp\/v2\/posts\/486\/revisions\/490"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/physics.iisc.ac.in\/~aksy\/wp-json\/wp\/v2\/media\/495"}],"wp:attachment":[{"href":"https:\/\/physics.iisc.ac.in\/~aksy\/wp-json\/wp\/v2\/media?parent=486"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/physics.iisc.ac.in\/~aksy\/wp-json\/wp\/v2\/categories?post=486"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/physics.iisc.ac.in\/~aksy\/wp-json\/wp\/v2\/tags?post=486"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
