Enhancement of graphene visibility on transparent substrates by refractive index optimization
H. Gonçalves, L. Alves, C. Moura +3
Optical reflection microscopy is one of the main imaging tools to visualize graphene microstructures. Here is reported a novel method that employs refractive index optimization in…
Enhancing visibility of graphene on arbitrary substrates by microdroplet condensation
Hugo Gonçalves, Michael Belsley, Cacilda Moura +2
In order to take advantage of the enormous potential of graphene for future electronic micro-circuits and other applications it is necessary to develop reliable, rapid and widely a…
Controllable transport mean free path of light in xerogel matrixes embedded with polystyrene spheres
Boris P. J. Bret, Nuno J. G. Couto, Mariana Amaro +2
Xerogel matrices, made by sol-gel techniques, are embedded with polystyrene spheres to promote multiple scattering of light. Varying the concentration of the spheres inside the mat…
Theory for a Hanbury Brown Twiss experiment with a ballistically expanding cloud of cold atoms
Jose Viana Gomes, Aurélien Perrin, Martijn Schellekens +3
We have studied one-body and two-body correlation functions in a ballistically expanding, non-interacting atomic cloud in the presence of gravity. We find that the correlation func…
