  title = {Do we understand the structure of the gallium-rich surface of GaAs(001)? Experimental and theoretical approaches},
  abstract = {While the As-rich 2 x 4 reconstruction of GaAs(001) is well explained by the so-called beta(2) structure, the atomic structure of the Ga-rich 4 x 2 phase has been discussed for a long time. In this review, the most important structural models for the GaAs(001) (4 x 2)/c(8 x 2) surface are compared from different theoretical and experimental points of view. The selected reconstructions include the recently proposed model, a new mixed dimer model, and the well-known beta, beta(2), Cerda and Skala zeta models. The different structures are compared on the basis of total energy calculations, simulations of STM experimental images and interpretation of X-ray diffraction data. Only the zeta model satisfies all criteria, and provides therefore a satisfactory explanation of the atomic structure of GaAs(001)-(4 x 2).},
