Measured spin-integrated EDCs for Pb/l-Si(111) (a) at k∥ = −0.11 Å−1 and at (b) k∥ = −0.24 Å−1 with Voigt profiles obtained from the self-consistent two-step fitting routine. (c, d) Corresponding spin polarization data and fits of the x, y and z components. Insets show the in-plane polarization vectors obtained from the two-step fit. (e, f) Parts of constant energy surfaces illustrating the measurement positions of the EDCs in reciprocal space. (g, h) Spin-resolved intensity profiles projected on the quantization axis for the two measured momenta.
