ENERGIZE
ENERGIZE /PM5
ENERGIZE is a collaboration between Helmholtz-Zentrum Berlin and the Humboldt Universität zu Berlin (HU). The aim of this project is to operate a beamline with a suitable end-station for materials science in the field of energy research. ENERGIZE is dedicated to research on hybrid materials and energy efficient technologies.
The dipole-PGM (plane grating mirror) beamline PM5 is optimized for the 20 eV to 1.5 keV energy range, which is ideally suited to perform ultraviolet photoelectron spectroscopy (UPS), X-ray photoelectron spectroscopy (XPS) and X-ray absorption spectroscopy (XAS) measurements. In addition, an attenuator system is installed, to allow measurements on radiation sensitive samples (<5 pA/cm² sample current).
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
Methods
ARPES, UPS, XPS, LEED, EXAFS, NEXAFS
