ARPES

We are setting-up a lab-based angular resolved photoemission spectroscopy (ARPES) equipment. The photons with energy ≈ 21.2 eV and ≈ 40 eV are supplied by HIS 13 helium lamp from Omicron. The base pressure in the analysis chamber ≈ 3x10-11 Torr. Sample can be installed on a cold finger thathas the base temperature ≈ 10 K.

The electron analyzer (below) is Scienta 200U.
