(a) Photoelectron diffraction pattern at the Fermi energy of a Ru(0001) surface. The first Brillouin zone and major symmetry points are indicated (Martín-García et al., 2015b). (b) LEED pattern of clean W(110) at 50 eV (5 µm electron beam diameter) and (c) profile across the (0,0) and (0,1) spots. |
