About our ARPES system

  • The ARPES system comprised of Scienta-Omicron DA30L hemispherical electron analyzer.
  • Base pressure of the system is ~1 ✕ 10-10 mbar.
  • A Scienta VUV-5k helium discharge lamp with monochromator is used as photon source.
  • Mott spin detectors are also available for spin-resolved band measurement.
  • The manipulator can be cooled down using either liquid nitrogen (sample temperature ~90 K) or liquid helium cryogen.
  • Single crystalline sample can be exfoliated or cleaved in the load-lock chamber (pressure ~5 ✕ 10-8 mbar).
  • Thin film samples can be grown in-situ using PLD.
  • Certain samples can be prepared by argon sputtering and annealing.
