Zusammenfassung

ABSTRACT:

Focusing light to a metallic AFM tip enables 20-nm-resolved optical images,
simultaneously with AFM topography. Any wavelength from visible to far-infrared and
even microwaves can be used, thus enabling contrast from vibration, phonon, plasmon,
and magnon resonances, to study chemical composition or electronic conduction, for
example, in 20-nm detail.

Biography:
Fritz Keilmann (born 1942) studied meteorology and physics in München and received a Dr. rer.
nat. for research on infrared plasma diagnostics. As postdoc of Ali Javan at MIT he developed
antenna-based harmonic mixing and high-power THz lasers. He has been a staff researcher of
the Max-Planck Society from 1973 to 2012: Initally at the MPI für Festkörperforschung Stuttgart,
he pioneered far-infrared nonlinear optics and spectroscopy of solids, and investigated phonon
physics, microwave biological effects, carrier dynamics of semiconductors, far-infrared
ellipsometry of superconductors, and cyclotron pumping of quantum-Hall edge states. In 1995
he relocated to the MPI für Biochemie Martinsried where he pioneered infrared scattering nearfield
microscopy, and also coherent Fourier-transform infrared spectroscopy using frequencycomb
beams. From 2007 - 2012 he was with the MPI für Quantenoptik Garching, in the DFG
Cluster "Munich-Centre for Advanced Photonics", developing broad- band infrared spectroscopic
near-field microscopy. He has been a guest researcher at UC Santa Barbara and UC San Diego.
He has been awarded the Kenneth J. Button prize 2009. Besides operating his firm LASNIX, he is
presently a Scientific Advisor to Neaspec GmbH, producer of near-field infrared microscopes, and
a Guest Researcher at LMU München investigating soft matter and biological nanocomposites.
