      abstract     = {Low-energy electron diffraction (LEED), scanning tunneling
                      microscopy (STM) and density functional theory (DFT)
                      calculations have been used to investigate the atomic and
                      electronic structure of gold deposited (between 0.8 and 1.0
                      monolayer) on the Pt(111) face in ultrahigh vacuum at room
                      temperature. The analysis of LEED and STM measurements
                      indicates two-dimensional growth of the first Au monolayer.
                      Change of the measured surface lattice constant equal to
                      2.80 Å after Au adsorption was not observed. Based on DFT,
                      the distance between the nearest atoms in the case of bare
                      Pt(111) and Au/Pt(111) surface is equal to 2.83 Å, which
                      gives $1\%$ difference in comparison with STM values. The
                      first and second interlayer spacing of the clean Pt(111)
                      surface are expanded by $+0.87\%$ and contracted by
                      $−0.43\%,$ respectively. The adsorption energy of the Au
                      atom on the Pt(111) surface is dependent on the adsorption
                      position, and there is a preference for a hollow fcc site.
                      For the Au/Pt(111) surface, the top interlayer spacing is
                      expanded by $+2.16\%$ with respect to the ideal bulk value.
                      Changes in the electronic properties of the Au/Pt(111)
                      system below the Fermi level connected to the interaction of
                      Au atoms with Pt(111) surface are observed.},
