A new dimension in chemical nanoimaging

22/02/2017

Researchers from the Basque institutions CIC nanoGUNE, Ikerbasque and Cidetec, and the German Robert Koch-Institut report the development of hyperspectral infrared nanoimaging. It is based on Fourier transform infrared nanospectroscopy (nano-FTIR) and enables highly sensitive spectroscopic imaging of chemical composition with nanoscale spatial resolution (Amenabar et al., Nat. Commun. 8, 14402 doi: 10.1038/ncomms14402 (2017)).

Grafenozko plasmoien detekzio elektrikoa terahertzen maiztasunetan

Uhin-luzera izugarri motzetan hedatzen dira terahertzen plasmoiak grafenozko xafla batean, zundazko ekortze-mikroskopio bidez lortutako fotokorrente-irudietan ikus daitekeen bezala.

Nanolight at the edge

21/03/2016

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.
