• surface ligands [14]. In this work, we obtain charge transfer on the atomic scale for size-dependent quantum-confined systems using core-hole clock (CHC) spectroscopy. We further expand the well-established CHC approach by the aspect of detecting the internal continuum states within the size-controlled

• states and the dynamical CT in the excited state can be probed by photoemission spectroscopy (PES). In particular, core hole clock spectroscopy has been used to measure the time constant of dynamical CT in the valence band states as a function of the lifetime of the core hole, which is typically of the
