Researchers from CIC nanoGUNE, in collaboration with ICFO and Graphenea, have demonstrated how infrared light can be captured by nanostructures made of graphene. This happens when light couples to charge oscillations in the graphene. The resulting mixture of light and charge oscillations – called plasmon - can be squeezed into record-small volumes – millions times smaller than in conventional dielectric optical cavities. This process has been visualized by the researchers now, for the first time, with the help of a state-of the-art near-field microscope and explained by theory. Particularly, the researchers identified two types of plasmons - edge and sheet modes - propagating either along the sheet or along the sheet edges. The edge plasmons are unique for their ability to channel electromagnetic energy in one dimension. The work - funded by the EC Graphene Flagship and reported in Nature Photonics - opens new opportunities for ultra-small and efficient photodetectors, sensors and other photonic and optoelectronic nanodevices.

Researchers of the Nanodevices group, in collaboration with groups from the CFM and DIPC, both institutions also located in Donostia-San Sebastián, have discovered a new magnetoresistance effect occurring in materials with strong spin-orbit coupling. This new effect has been recently reported in the prestigious journal Physical Review Letters and featured as an Editor’s Suggestion.

An international team led by Miguel M. Ugeda (CIC nanoGUNE) and Michael F. Crommie (UC. Berkeley (USA)) has demonstrated the coexistence of superconductivity and charge density wave (CDW) order in a single layer of NbSe₂, a model transition metal dichalcogenide (TMD) metal. The demonstration that a single layer of NbSe₂ is a true 2D superconductor is a breakthrough in the field of 2D materials. Very few 2D superconductors exist in nature, and single-layer NbSe₂ is the first among them that remains a superconductor in its isolated, 2D form without the need of a special substrate. Furthermore, CDW order - spatial modulation of both the electron density and the atomic lattice (see figure below) – has been revealed to be a genuine 2D electronic phenomenon in NbSe₂. This work has been recently reported in Nature Physics.
