Extended Data Fig. 1

This setup is composed of four sub-systems: a laser source for light excitation, a dark-box for optical filtering, polarization control and alignment, a low-temperature UHV STM for sample preparation and characterization with a built-in lens for both light excitation and collection, and a photon detection sub-system containing a SPAD for PL intensity measurements and a spectrometer equipped with a highly sensitive CCD detector for PL spectral measurements.
