nanoGUNE reaches new depths in infrared nanospectroscopy

20/07/2020

Researchers from the Nanooptics Group at CIC nanoGUNE demonstrate that nanoscale infrared imaging – which is established as a surface-sensitive technique – can be employed for chemical nanoidentification of materials that are located up to 100 nm below the surface. The results further show that the infrared signatures of thin surface layers differ from that of subsurface layers of the same material, which can be exploited to distinguish the two cases. The findings, recently published in Nature Communications, push the technique one important step further to quantitative chemometrics at the nanoscale in three dimensions.

Researchers discover directional and long-lived nanolight in a 2D material

Nanolight
25/10/2018

An international team led by researchers from Monash University (Melbourne, Australia), University of Oviedo (Asturias, Spain), CIC nanoGUNE (San Sebastián, Spain), and Soochow University (Suzhou, China) discover squeezed light ('nanolight') in the nanoscale that propagates only in specific directions along thin slabs of molybdenum trioxide – a natural anisotropic 2D material –. Besides its unique directional character, this nanolight lives for an exceptionally long time, and thus could find applications in signal processing, sensing or heat management at the nanoscale.

Argia “hankaz gora” jarri du euskal ikertzaile-talde batek

23/02/2018

CIC nanoGUNEko ikertzaile batzuek, Donostia International Physics Centerrekin (DIPC) eta Kansas Estatuko Unibertsitatearekin (AEB) lankidetzan, “metagainazal hiperboliko” izeneko gainazalaren garapena argitaratu dute Science aldizkari ospetsuan. Gainazal horretatik, argi-uhinak forma erabat ezohikoekin hedatzen dira. Argia doitasun handiagoz kontrolatzeko eta monitorizatzeko bidean erdietsitako lorpen zientifiko hori garrantzitsua da oso, seinaleak detektatzeko eta prozesatzeko gailu optikoak miniaturizatzeko erronka teknologikoan aurrera egiteko

Hutsean, abiadura berean mugitzen da beti argia, segundoko 300 milioi metro baino gutxixeagoan. Ingurunez aldatuz gero, ordea, abiadura ere aldatu egin daiteke. "Hiperbolikoak" deritzen material oso berezi batzuetan argia nola hedatzen den ikertu dute CIC nanoGUNEn (zehazki, boro nitruroko geruza oso fin batzuetan), eta aurkikuntza hau egin dute: motelago higitzen da argia, eta "korrontearen kontra". Nature Photonics aldizkarian argitaratu dute lana Nanooptika eta Nanogailuen taldeetako ikertzaileek (Europako Batasuneko Graphene Fragship proiektuak diruz lagundu du), Bartzelonako ICFOko zenbait kiderekin batera.

Rainer Hillenbrand receives ERC starting grant

07/07/2010

The European Research Council (ERC) has awarded a Starting Grant to the TERATOMO proposal presented by Rainer Hillenbrand. The grant has a budget of nearly 1.5 M€ for a 5 year work program. TERATOMO is the acronym for Near-field Spectroscopic Nanotomography at Infrared and Terahertz frequencies. The core objective of the project is the development of a novel microscopy technique for three-dimensional imaging of nanostructures with infrared and terahertz light.
