We are interested in the spatio-temporal response of solid state surfaces, nanostructures, and molecules following ultrafast laser excitation. Our goal is to obtain an atomistic understanding of such photoinduced processes on (sub-) nanometer length and femtosecond time scales by employing novel pump-probe schemes for ultrafast scanning probe microscopy (SPM). We envision to study, drive and control solid state matter in highly non-equilibrium states on ultrashort length und ultrafast time scales.

To achieve this goal, we are putting efforts into the development of a broadband THz-STM combined with femtosecond optical excitation. For more information please check our research page and follow our news below.

Paper accepted in ACS Photonics, demonstrating the generation and time-domain sampling of ultrabroadband single-cycle THz bias pulses in an STM junction. Our results demonstrate the suitability of spintronic THz emitters for future ultrabroadband THz-STM applications with state-of-the art MHz laser systems, and provide insight into the broadband coupling of coherent THz radiation into nanoscale metallic junctions.
