GELEM-PES

PES operated by the German-Eastern European Laboratory for Energy Materials Research

The GELEM photoemission station is very flexible and demonstrate reliable performance for the whole variety of experiments of broad GELEM user community. Having several preparation chambers, fast-load systems, a number of insertion devises such as a flash-machine, evaporators, a cleavage system, a heating stage, a gas-inlet system etc., the station is a powerful instrument allowing to study fundamental properties of matter.

Selected Applications:
  • Research addresses electronic, chemical and structural properties of wide variety of materials and covers rather broad field of disciplines, scientific areas and applications: energy materials, conductive polymers for electrochemical applications, compositionally complex alloys, biomimetic materials, etc.
