A apresenta\u00e7\u00e3o ser\u00e1 realizada pelo professor do Departamento de F\u00edsica e Astronomia da Texas A&M University, Alexey Belyanin<\/a>, a convite do professor do SEL, Ben-Hur Viana Borges.<\/p>\n Com dura\u00e7\u00e3o estimada de 60 minutos, a palestra ser\u00e1 ministrada em l\u00edngua inglesa, aberta ao p\u00fablico e n\u00e3o h\u00e1 necessidade de inscri\u00e7\u00e3o para participar.<\/p>\n Saiba mais no resumo a seguir.<\/p>\n Recently there has been a surge of interest in 2D materials with properties drastically different from the same materials in the bulk form. Notable examples include graphene, surface states in topological insulators, and monolayers of transition metal dichalcogenides (TMDs). In this talk we discuss some of the exciting and unique optical properties of these 2D electron systems. We show that massless Dirac electrons in graphene give rise to an extremely strong mid\/far-infrared optical nonlinearity, perhaps the highest among known materials. Giant optical nonlinearity enables efficient generation of terahertz radiation, excitation of coherent surface plasmons, and tip-enhanced nonlinear spectroscopy utilizing surface plasmons which provides nanometer spatial resolution and femtosecond time resolution. Quantum optics of graphene and TMD monolayers promises efficient generation of polarization-entangled light, entangled plasmon-polaritons, and spin\/valley-entangled exciton states. We will also discuss feasibility of lasers and other optoelectronic devices based on these fascinating materials. <\/em><\/p>\n [+] informa\u00e7\u00e3o<\/p>\n Departamento de Engenharia El\u00e9trica e de Computa\u00e7\u00e3o da EESC Tel.: (16) 3373-8275 E-mail: departamento.eletrica@eesc.usp.br<\/a><\/a><\/p>\n Por Assessoria de Comunica\u00e7\u00e3o da EESC Imagem: Adapta\u00e7\u00e3o de Texas A&M University<\/p>\n","protected":false},"excerpt":{"rendered":" Todos os interessados em dispositivos \u00f3pticos e suas aplica\u00e7\u00f5es est\u00e3o convidados para assistir \u00e0 palestra Optics and plasmonics of graphene and other 2D materials<\/em>, que acontece nesta quarta-feira, dia 13, \u00e0s 14 horas, no Anfiteatro Armando Toshio Natsume do Departamento de Engenharia El\u00e9trica e de Computa\u00e7\u00e3o (SEL) da Escola de Engenharia de S\u00e3o Carlos (EESC) da USP.<\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"footnotes":""},"categories":[37],"tags":[],"class_list":["post-10464","post","type-post","status-publish","format-standard","hentry","category-noticias","entry"],"_links":{"self":[{"href":"https:\/\/eesc.usp.br\/comunicacao-admin\/index.php?rest_route=\/wp\/v2\/posts\/10464","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/eesc.usp.br\/comunicacao-admin\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/eesc.usp.br\/comunicacao-admin\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/eesc.usp.br\/comunicacao-admin\/index.php?rest_route=\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/eesc.usp.br\/comunicacao-admin\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=10464"}],"version-history":[{"count":0,"href":"https:\/\/eesc.usp.br\/comunicacao-admin\/index.php?rest_route=\/wp\/v2\/posts\/10464\/revisions"}],"wp:attachment":[{"href":"https:\/\/eesc.usp.br\/comunicacao-admin\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=10464"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/eesc.usp.br\/comunicacao-admin\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=10464"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/eesc.usp.br\/comunicacao-admin\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=10464"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
