Electronic contacts at the atomic scale for future graphene-based electronics

Due to its exceptional conduction properties, graphene has been proposed as a candidate to replace silicon in future electronics. However, several problems need to be overcome prior to its implantation in the production chain. Among these difficulties, one of the most fundamental unknown aspects is how to contact graphene with…

Sequential formation of N-doped nanohelicenes, nanographenes and nanodomes by surface-assisted chemical (cyclo)dehydrogenation of heteroaromatics

The use of appropriately functionalized molecular building blocks to form novel nano-architectures with tailored structure and electronic properties has recently been brought under the spotlight. Recently, the ESISNA group has developed an effective way of exploiting on-surface chemistry to grow different nanostructures in sequential steps from the same molecular precursor. We have used different activation temperatures to…

On the origin of interstellar aromatic molecules

Despite their abundance and ubiquity in space, the origin of polycyclic aromatic hydrocarbons (PAHs) is still a mystery for astronomers. Gas phase chemistry models, this is, simple collisions between C atoms and C-containing molecules, and soot formation mechanisms can not easily account for the observed amount of PAHs, as they…
