Topological insulators are electronic materials that have a bulk band gap like an ordinary insulator but have conducting states on their edge or surface. The conducting surface is not what makes topological insulators unique, but the fact that it is protected due to the combination of spin-orbit interactions and time-reversal symmetry. Researchers are chasing efficient […]

Since the discovery that graphene, the two dimensional carbon allotrope, can be isolated and incorporated into electronic devices intense research efforts have been triggered. Driving forces behind the experimental and theoretical studies of graphene are, e.g., the exceptional electronic properties, in particular the high electron mobilities, the long spin coherence lengths and the possibility to […]

We know that incident light can provoke a strong optical response in metallic nanostructures due to the excitation of resonant plasmonic modes, i.e, the electrons in the metal become excited by the photons in the incident light and oscillate collectively. Plasmonic nanoparticles can significantly modify the optical properties of nearby organic molecules and thus present […]

Graphene nanoribbons (GNRs), are strips of graphene with ultra-thin width (<50 nm). Graphene ribbons were introduced as a theoretical model by Mitsutaka Fujita and coauthors to examine the edge and nanoscale size effect in graphene. GNRs are very interesting structures, partly due to their attractive electronic properties. Those properties vary dramatically with changes in the […]
