The two-dimensional electronic energy bands of an ordered Cl overlayer on GaAs (110) were mapped by angle-resolved photoemission spectroscopy with synchrotron radiation. The results were compared to bands calculated with an empirical tight-binding approach. This comparison shows that the Cl adatoms are bound to As atoms and that the substrate atoms are relaxed from their positions in a way qualitatively similar to that of clean-surface GaAs (110).
