Grafeno epitaxial sobre sic(0001): crescimento, intercalação e efeitos de interface
(Universidade Federal de Minas GeraisUFMG, 2019-08-09)
In this work we investigate the influence of the graphene-substrate interface on the electronic properties of quasi-free-standing (QFS) bilayer graphene grown on silicon carbide (SiC). The QFS bilayers were developed by ...
Caracterização estrutural da interface grafeno/SiC após intercalação de oxigênio
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE FÍSICAPrograma de Pós-Graduação em FísicaUFMG, 2022-03-18)
The electronic and structural properties of low-dimensional materials, such as graphene, are highly related to the characteristics of the interface between them and the substrate where they are found. In this work we study ...
Crescimento de "multicamadas" de grafeno epitaxial em substratos de SiC à pressão atmosférica
(Universidade Federal de Minas GeraisUFMG, 2011-03-10)
In this work, we investigate the growth process and structure of epitaxial graphene grown on the C-face of silicon carbide (SiC) substrates. The growth was performed at atmospheric pressure in a furnace with an Argon (Ar) ...
Propriedades estruturais e eletrônicas de bicamadas de grafeno epitaxial e nanoestruturas do isolante topológico Bi2Se3
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE FÍSICAPrograma de Pós-Graduação em FísicaUFMG, 2020-12-18)
Low dimensional materials, such as graphene, are highly susceptible to the substrate (interface) where they are supported. In this work, we investigate the properties of epitaxial graphene bilayers on oxidized silicon ...
Crescimento, propriedades estruturais e eletrônicas de grafeno epitaxial
(Universidade Federal de Minas GeraisUFMG, 2012-05-07)
This thesis presents studies on the structural properties of multilayeredfilms of epitaxial Graphene grown on silicon carbide (on both polar faces of the substrate). In the first study we have identified the existence of ...
Estudo por microscopia/espectroscopia de tunelamento e difração de raios x da correlação entre propriedades estruturais e eletrônicas de grafeno epitaxial sobre cobre
(Universidade Federal de Minas GeraisUFMG, 2016-03-02)
In this work we have used atomically-resolved scanning tunneling microscopy and spectroscopy to study the interplay between atomic and electronic structure of graphene formed on copper via chemical vapor deposition. In ...
