ENERGIZE

ENERGIZE /PM5

ENERGIZE is a collaboration between Helmholtz-Zentrum Berlin and the Humboldt Universität zu Berlin (HU). ENERGIZE is dedicated to research on hybrid materials and energy efficient technologies.

The dipole-PGM (plane grating mirror) beamline PM5 is optimized for the 30 eV to 1.5 keV energy range, which is ideally suited to perform ultraviolet photoelectron spectroscopy (UPS, ARPES), high-resolution X-ray photoelectron spectroscopy (XPS) and X-ray absorption spectroscopy (XAS) measurements in total electron yield (TEY) and Auger electron yield (AEY) modes. In addition, an attenuator system is installed, to allow measurements on radiation sensitive samples.

Selected Applications:
  • Fundamental research into the electronic structure of new materials such as perovskite and 2D semiconductors
  • Optimization of interfaces in light emitting diodes, solar cells and photoelectrochemical elements for the production of storable fuels
  • Optimization of interfaces of opto-electronic components printed in air
