Adsorption of Zn on the GaAs(001)-(2×4) surface has been studied by reflection high-energy electron diffraction (RHEED) and total-reflection-angle x-ray spectroscopy in real time. Adsorption sites of Zn atoms on the (2×4) surface have been determined using rocking-curve analysis of RHEED. The exposure of the (2×4) surface to a Zn beam results in the preferred adsorption of Zn at Ga-vacancy sites in the missing dimer trenches of the (2×4) unit cell. The amount of adsorbed Zn atoms under a Zn flux has been estimated to be ∼0.50 and ∼0.20 monolayers at 200 and 250°C, respectively.
