Atomistic simulations at two levels, classical and quantum-mechanical, are performed to probe the binding possibilities of the smallest multi-shelled concentric fullerenes, known as “carbon onions”. We focus on the binding behavior of adjacent ca

Monte Carlo simulations and tight-binding calculations shed light on the properties of three-dimensional nanographene, a material composed of interlinked, covalently-bonded nanoplatelet graphene units. By constructing realistic model networks of nano

We use computer simulations to study the behavior of amorphous carbon and carbon composites under tensile strain. We investigate the behavior of the optoelectronic properties of these materials as strain is increased. These properties are monitored t

In this review, we present our recent computational work on carbon-based nanostructured composites. These materials consist of carbon crystallites embedded in an amorphous carbon matrix and are modeled here through classical and semi-empirical quantu

Tight-binding calculations shed light onto the link between disorder and optical properties in pure amorphous carbon films. It is shown that the Urbach energy E-boolean OR is an excellent probe of disorder in such films. Our striking finding is that

Atomistic simulations give new insights into the properties of carbon nanofoams, a low-density nanoporous and nanostructured material. It is shown that agglomeration, crosslinking, and deformation, processes that are often ignored in theoretical desc

A tough material commonly used in coatings is diamond-like carbon (DLC), that is, amorphous carbon with content in four-fold coordinated C higher than ∼70%, and its composites with metal inclusions. This study aims to offer useful guidelines for th

We employ empirical tight-binding simulations on strained tetrahedral amorphous carbon and diamond nanocomposite networks. For each applied strain, the optoelectronic properties are monitored through the absorption coefficient and the dielectric func

We present in this work a theoretical framework based on the tight-binding method, which is able to probe at a local atomic level the optoelectronic response of nanomaterial systems and link it to the associated disorder. We apply this methodology to
