Description

This dataset contains X-ray spectroscopic data of PbS quantum dots of varying sizes, PbS bulk reference materials (thin film and Galena crystal) and PbI2 reference material. Hard X-ray Spectroscopy (HAXPES) data is found for all samples for materials characterization in the S2p, Pb4f and I4d core level region. Resonant Auger Spectroscopy data is found for all samples in the Pb MNN region.

Data collection
  • Description of the mode of collection: Description of methods used for collection/generation of data: Resonant Auger maps were collected by measuring Auger spectra in the Pb MNN electron kinetic energy region for multiple photon energies over the Pb M-edge. The measurements were conducted at the High Kinetic Energy (HIKE) end-station at the KMC-1 beamline at the synchrotron BESSY II, using a Scienta R4000 hemispherical electron energy analyzer.
  • Time period(s) for data collection: 2021-05-11 – 2024-08-30
  • Instrument: KMC-1 beamline at the synchrotron BESSY II, using a Scienta R4000 hemispherical electron energy analyzer
