Abstract

English

Combining both worlds of momentum and real-space time-resolved momentum microscopy, this thesis introduces a new approach to probe the entire exciton landscape and dynamics of twisted TMD heterostructures with momentum-, spatial-, spectral- and temporal-resolution and paves the way for new types of experiments with spatio-spectral and spatio-temporal capabilities, which are showcased in two publications of this manuscript-based PhD thesis.
Keywords: trARPES; TMD heterostructures; dark-field momentum microscopy; time-resolved momentum microscopy; moiré physics; exciton dynamics
