Grafeno em substratos transparentes dielétricos para aplicações fotônicas
(Universidade Presbiteriana Mackenzie, 2017-05-04)
Graphene is a two-dimensional material composed of carbon atoms arranged in a hexagonal lattice with excellent electronic properties, such as high electron mobility, and optical properties, such as wavelength-independent ...
Nanocompósito de óxido de grafeno e nanopartículas metálicas para espectroscopia raman amplificada por superfície (SERS)
(Universidade Presbiteriana Mackenzie, 2017-01-24)
Light interaction with the electronic cloud of metallic nanoparticles at frequencies that are resonant with the natural oscillation frequency of the cloud is known to excite localized surface plasmons. This phenomenon is ...
Otimização da sensibilidade à pressão de fibras de bandgap fotônico
(Universidade Presbiteriana Mackenzie, 2014-02-18)
This work deals with the study of the sensitivity to pressure and temperature of photonic crystal fibers aiming at applications in distributed sensing. Although PCFs allow for distributed measurement, just as conventional ...
