is both user-friendly and powerful for data analysis (and even for interfacing experiments). For simplicity, we will work only along one momentum direction, hence using k = k, and will take the lattice constant as 1 A, hence the edges of the Brillouin zone at k= ˇ.

Au(111) data recorded with DA30-L, 2D Ferrum VLEED detector, the VUV5k UV source and using the analyser deflector capability for ARPES and Spin mapping. The complete ARPES data cube was recorded in 10 min and the high resolution Spin measurement to the right was recorded in 2 h, all with fixed sample/manipulator position.

These can be measured with the angular-resolved photoemission station (ARPES) at BESSY II. Left image shows the sample temperature at 25 K, right at only 1 K. The energy distribution of the conducting and valence band electrons can be derived from these data. The surface remains conductive at very low temperature (1 K). Credit: Helmholtz

ARPES is a photon-in electron-out spectroscopy based on the photoelectric effect. An incoming photon, generated in x-ray sources or laser systems, is directed at a sample where it is absorbed. If the photon supplies sufficient energy to the electron it can overcome the work function and exit the sample as a photoelectron.
