Journal ArticleDOI
Au nanotip as luminescent near-field probe.
Sebastian Jäger,Andreas M. Kern,Mario Hentschel,Regina Jäger,Kai Braun,Dai Zhang,Harald Giessen,Alfred J. Meixner +7 more
TL;DR: A new optical near-field mapping method utilizing the plasmon-mediated luminescence from the apex of a sharp gold nanotip, which acts as a quasi-point light source which does not suffer from bleaching and gives a spatial resolution of ≤25 nm.
Journal ArticleDOI
Nanoantenna-Enhanced Infrared Spectroscopic Chemical Imaging
Lucca Kühner,Mario Hentschel,Ute Zschieschang,Hagen Klauk,Jochen Vogt,Christian W. Huck,Harald Giessen,Frank Neubrech,Frank Neubrech +8 more
TL;DR: The results demonstrate the potential of nanoantenna-enhanced spectroscopic infrared chemical imaging for spatially resolved characterization of organic layers with thicknesses of several nanometers and provides chemical selectivity, which would not be available with plasmonic imaging that is based on refractive index sensing.
Journal ArticleDOI
Plasmonic antennas, positioning, and coupling of individual quantum systems
Daniel Dregely,Klas Lindfors,Klas Lindfors,Jens Dorfmüller,Mario Hentschel,Mario Hentschel,Merle Becker,Jörg Wrachtrup,Markus Lippitz,Markus Lippitz,Ralf Vogelgesang,Harald Giessen +11 more
TL;DR: In this paper, the authors used top-down fabrication techniques to achieve positioning of individual quantum emitters relative to plasmonic nanostructures with an accuracy better than 10nm.
Journal ArticleDOI
Electrons Generate Self-Complementary Broadband Vortex Light Beams Using Chiral Photon Sieves.
TL;DR: This work designs, fabricate, and characterize self-complementary chiral structures made of holes in an Au film and generate light vortex beams with specified angular momentum orders that can form the basis for the generation of structured-light electron-driven photon sources.
Journal ArticleDOI
Ultrasensitive Tip- and Antenna-Enhanced Infrared Nanoscopy of Protein Complexes
TL;DR: In this article, surface-enhanced infrared absorption (SEIRA) using resonant plasmonic nanoantennas enables zeptomolar detection sensitivity of (bio)analytes, although with diffraction limited spatial resolution.
