Graphene deposited on planar surfaces often exhibits sharp and localized folds delimiting seemingly planar regions, as a result of compressive stresses transmitted by the substrate. Such folds alter the electronic and ...

[ANGLÈS] This project presents a study for both optic and electronic properties of graphene and possible variations of different physical magnitudes that are produced in a material when a single layer of graphene is deposited ...

Two-terminal tandem cell architectures are believed to be an effective way to further improve the power conversion efficiency in solution processed photovoltaics. To design an efficient tandem solar cell, two key issues ...

We demonstrate direct growth of two-dimensional (2D) and three-dimensional (3D) graphene structures on glass substrates. By starting from catalytic copper nanoparticles of different densities and using chemical vapour ...

We demonstrate the direct transfer of graphene from Cu foil to glass and flexible substrates such as PET, using polyimide (PI) mixed with an aminosilane (3-aminopropyltrimethoxysilane) or only PI, respectively, as intermediate ...

Low density polycarbonate foams containing different amounts of graphene nanoplatelets with variable cellular morphologies were prepared using a supercritical carbon dioxide two-step foaming process, which consisted of the ...

Nonlinear optical processes rely on the intrinsically weak interactions between photons enabled by their coupling with matter. Unfortunately, many applications in nonlinear optics are severely hindered by the small response ...

Energy decay plays a central role in a wide range of phenomena1,2,3, such as optical emission, nuclear fission, and dissipation in quantum systems. Energy decay is usually described as a system leaking energy irreversibly ...

We propose a simple approach to couple light into graphene plasmons and focus these excitations at focal spots of a size determined by the plasmon wavelength, thus producing high optical field enhancement that boosts the ...

Ante el reciente descubrimiento del grafeno, un nuevo material con propiedades de gran interés tecnológico, la industria busca optimizar sus mecanismos de producción con el objetivo de abordar un mercado para el cual se ...
