Structural Aspects of Thiol-Like SAMs

Among the factors crucial for a SAM structure, the thiol-substrate bond has been a subject of particular controversy over more than 15 years. It is worth discussing the SAM/substrate interface in some detail since it is important not only for understanding SAM structures in general but also for electrochemical metal deposition when metal is intercalated at the SAM/Au interface (Section 5.4.3). As indicated above we limit the discussion to SAMs on Au(l 11) as this is the interface where theoretical and experimental work is sufficiently detailed to allow for a discussion at the atomic level. 

1) In addition to the stress by lattice mismatch there are additional electrostatic effects arising from charge redistribution [97, 98]. 

Up to now the discussion has focused on basic properties of SAMs inherent to the particular combination of SAM-forming molecule and substrate, as well as environmental
