The Enrique Pérez-Payá Prize of the Spanish Biophysical Society has been awarded to Raul Perez-Jimenez, leader of CIC nanoGUNE’s Nanobiomechanics Group, “for his studies of the mechanical properties of biological macromolecules”.
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.
Itxasne Azpitarte has been nominated as top student in the 2014/2015 academic year in the Master’s degree in New Materials, which is run between various university departments of the UPV/EHU-University of the Basque Country and the University of Cantabria (UC).
Researchers from the Nanooptics group at CIC nanoGUNE in collaboration with colleagues at ICFO - The Institute of Photonic Sciences (Catalunya) developed a new non-invasive room-temperature technique for graphene device characterization. This work has been funded by the EC Graphene Flagship and was recently reported in Nature Communications.
