A review of graphene oxide, graphene buckypaper, and polymer/graphene composites: Properties and fabrication techniques
(Sage Publications Ltd, 2016-10-01)
In this critical review, the preparation methods, unique properties, and graphene oxide structure as well as graphene have been interpreted. Various aspects for the graphene oxide reactivity were also discussed. Graphene ...
Role of Van der Waals forces in graphene adsorption over: Pd, Pt, Ni
(Soc Brasileira Fisica, 2013-06)
We report ab initio computations with the Vienna Ab initio Simulation Package (VASP) aimed at elucidating the adsorption mechanism of graphene-like structures on (111) Pd, Pt, and Ni surfaces. To study the adsorption ...
Photo-electrons unveil topological transitions in graphene-like systems
(Nature Publishing Group, 2016-11-11)
The topological structure of the wavefunctions of particles in periodic potentials is characterized by the Berry curvature Ωkn whose integral on the Brillouin zone is a topological invariant known as the Chern number. The ...
Electronic transport upon adsorption of biomolecules on graphene
(Wiley, 2019)
Currently, the construction of sensors plays an important role in electronics and bioelectronics, due to the wide range of novel applications for biomedical research, food quality control and environmental monitoring. The ...
Dynamical screening of van der Waals interaction between graphene layers
(Iop Publishing, 2012-04)
The interaction between graphene layers is analyzed combining local orbital DFT and second order perturbation theory. For this purpose we use the Linear Combination of Atomic Orbitals -Orbital Occupancy (LCAO-OO) formalism, ...
Improving Graphene-metal Contacts: Thermal Induced Polishing
(Cambridge Univ Press, 2018-01-01)
Graphene is a very promising material for nanoelectronics applications due to its unique and remarkable electronic and thermal properties. However, when deposited on metallic electrodes the overall thermal conductivity is ...
Otimização de parâmetros de processo para a obstentação de monocamadas de grafeno e estruturas grafite/grafeno-likeParameters optimization to obtain graphene monolayers and graphite/graphene-like structures
(Pós-Graduação em Ciência e Engenharia de Materiais, 2017)
Group IV Graphene- and Graphane-Like Nanosheets
(AMER CHEMICAL SOC, 2011)
We performed a first-principles investigation on the structural and electronic properties of group IV (C, SiC, Si, Ge, and Sn) graphene-like sheets in flat and buckled configurations and the respective hydrogenated or ...
