Mikkelsen | | Affilation: | KISTI, KR | | Pages: | 458 - 461 | | Keywords: | STM, simulation, adsorption, DFT | | Abstract: | We have studied the GaAs(111)B surface with Au deposited either homogeneously or as nanoparticles, and found the presence of Au in either form to give rise to a $(sqrt(3} ! imes! sqrt(3} )$ Au-induced surface reconstruction. In the structural model supported by our DFT calculations for an Au coverage of 1/3 ML, Au atoms are adsorbed at every third threefold hollow hcp site of the Ga lattice. The proposed structural model is in agreement with experimental data from low-energy electron diffraction and STM. | | ISBN: | 1-4200-6182-8 |
