The structure of gold nanoparticles and Au based thiol self-organized monolayers

This is the authors' abstract. We don't add key points for this paper.

Spatial and electronic structure of gold nanoparticles (AuNPs) and AuNPs with thiol base self-assambled monolayers (SAMs) are reviewed. Theoretical and experimental data on the symmetry, bond lengths, band gaps and binding energies are presented. Coordination of sulfur and its compounds to Au structures and AuS bond length emphasized especially. The works on synthesis of thiol based SAMs on AuNPs are reviewed. The applications of EXAFS and photoelectron spectroscopy for the investigated SAMs on AuNPs are considered.
