Femtosecond nano-videography of interlayer charge transfer in van der Waals heterostructures

Tunneling between atomic layers strongly changes the polarizability of electron-hole pairs in van der Waals heterobilayers. By monitoring this dynamics with a near-field microscope, we record subcycle nano-movies of local tunneling processes even in insulators.
