Figure 2
(a) Schematic top view of the rotatable ARPES system in the p-polarization geometry. The measurement chamber equipped with a hemispherical electron analyzer can be rotatable around the light path (0 ≤ Ψ ≤ 90°) by using two differentially pumped rotary feedthroughs (DPRFs). (b) Schematic view of the ARPES geometry, where the p-polarized light is incident on the photoelectron detection plane that is equivalent to the mirror plane of the sample. The polar, tilt and azimuthal angles of the sample are denoted as θ, ϕ and φ, respectively.
