• rougher and a flatter gold substrate on the lateral variation of the conductivity. We find that the roughness of the substrate crucially defines this variation. We conclude that it is paramount to adequately choose a gold substrate for investigations on molecular layer conductivity. Keywords: Au/mica; Au

• to carry out the measurements. As mentioned above, two types of Au substrates were used, that is, Au-coated Si (Au/Si) and epitaxially grown Au on mica (Au/mica), bought from Sigma-Aldrich and Phasis, respectively. The Au thicknesses are 200 nm for Au/mica and 100 nm for Au/Si substrates. The Au/mica

• . The bare substrates were investigated as a reference for the measurements thereafter. They show topographies and current maps characteristic for Au/Si and Au/mica. Subsequently, it was observed how these characteristics change with SAMs deposited onto the surface. A strong resemblance between bare and

• cleavage of C–H bonds and the subsequent formation of new C–C bonds between neighboring molecules also seems to play a crucial role in the EBISA process. Previous studies showed that iron nanostructures fabricated on top of a cross-linked SAM on Au/mica can be transferred to solid substrates and grids

The PAT SAM-Au/mica substrate was placed into the solution and allowed to stand for 30 min in order to avoid thermal drift of the sample during grafting

• generation of ultraflat Au substrates through the template-stripping method [59][60], it is a limiting factor for our scheme. Even though transfer using Au/mica can be achieved to some extent, the parameters must be so narrowly defined as to prohibit a reliable, routinely applicable process. By using silver
