Subcycle contact-free nanoscopy of tunnelling electrons
In collaboration with the group of Jaroslav Fabian (UR) and together with Tyler Cocker and Jessica Boland, researchers at RUN have implemented a novel concept to map out ultrafast interlayer tunneling and recombination dynamics of excitons in van der Waals heterostructures in a contact-free manner. The new technique provides spatiotemporal access to tunnelling processes in insulating, conducting, or superconducting systems, on nanometer length and femtosecond time scales, conceptually bridging the gap between near-field microscopy and light-wave driven STM.
The results have been published in Nature Photonics.
