1 cubed ARPES

Thisicxcyxc experiment is built in a collaborative effort by the IFW Dresden, TU Dresden and the HZB, to enable experiments that require the highest energy resolution at ultimately low sample temperatures. To achieve this goal, all contributions to experimental broadening ---the resolution of both the excitation source and the electron energy analyzer as well as the sample temperature--- have been reduced to ≤1 meV or their equivalent, yielding the name of the station: 1 meV x 1 meV x 1 K = 13.

Key characteristics

•  High-flux, high-resolution plane grating monochromator beam-line.

•  Unique purpose-built 3He cryostat allows for sample temperatures below 1 K.

•  High-resolution Scienta R4000 electron energy analyzer.


While samples are typically prepared by in-situ cleaving on the cryomanipulator, the system is equipped with a preparation chamber with a number of facilities for preparation and characterization:

•  LEED optics.

•  Ion-gun for sample cleaning.

•  Low-temperature (< 750 K) sample heating stage.

•  Facility for direct current heating of semi-conducting samples.

•  Evaporators can be mounted on the preparation chamber on request.
