Angle resolved photoemission spectra (ARPES) I(E – EF, k∥), where k∥ is along the [11̅0] direction (parallel to the wires), of (a) clean Au(887) and of (b) the oriented PPP/Au(887) interface. (c) Constant energy map I(k∥, k⊥) at E – EF = −1.04 eV of clean Au(887) (left) and of the oriented PPP/Au(887) (right). (d) Zoom-in of the spectra in (b). Arrows and dashed lines highlight peculiar features, see text for details.
