Espectroscopia raman em materiais bidimensionais
(Universidade Presbiteriana Mackenzie, 2017-12-15)
In this thesis, the properties of four kinds of layered materials were investigated: twisted bilayer graphene, black phosphorus, germanium selenide (GeSe) and germanium sulfide (GeS) (group IV monochalcogenides) by ...
Plásmon poláritons de superfície em grafeno sobre um substrato com épsilon próximo a zero
(Universidade Presbiteriana Mackenzie, 2019-07-29)
In this work, a method to facilitate the excitation of surface plasmon polaritons in graphene is proposed and demonstrated by using a substrate with its dielectric fuction close to zero. Silicon carbide was used as the ...
