Dynamics of Nanoelectronic Systems

Former Independent Max Planck Research Group - Dr. Sebastian Loth

We study dynamical processes in nanostructures. Of particular interest is the question how quantum confinement and enhanced electron-electron interaction modify the time-dependent evolution of low-energy excitations in nanomagnets, molecules and charge-ordered surfaces.

For this purpose we employ a novel combination of scanning tunneling microscopy and all-electronic pump-probe spectroscopy. This tool is ideally matched to the energetic, spatial and temporal scales of nanoelectronic systems. The ability to tune pulse energies in the 1 meV range will efficiently complement experiments on high-energy light sources such as free-electron lasers and synchrotrons.

It is our goal to push the boundaries of time resolution in scanning tunneling microscopy to uncover dynamical processes in the electronic properties of nanostructures and surfaces at atomic dimensions.

Our group has moved to the University of Stuttgart you can find us now at the Institute for Functional Matter and Quantum Technologies:
