Phoibos 100, Specs

Equipment: Phoibos 100, Specs
Technique:  Ultraviolet and X-ray photoelectronspectroscopy
Acquisition year: 2002
Responsible: Carsten Habenicht /

Description: UPS (ultraviolet photoelectron spectroscopy) can measure HOMO position, ionization potential and vacuum level of metals and semiconducting materials. XPS (x-ray photoelectron spectroscopy) can measure core level shifts and elementary composition of surfaces. Possible to heat (tungsten wire) and cool (N2) the sampleholders during measurement


  • Custom-made sample holder
  • samples on Au or Ag foil
  • Sputter system to clean surfaces
  • He 21.2eV source
  • Al cathode for X-ray
  • Measurement in UHV (10e-11mbar)
  • Software for peak fitting and database for material composition determination
