    • 11-S-TFA is the acetyl-protected derivative (see Supporting Information). While this compound could also be used for monolayer preparation, removal of the acetyl group would require harsher conditions such as heating at reflux for several hours in acidic solutions.

    • It cannot be ruled out that disulfides form under the basic conditions used for removal of the TFA group, as the binding energy of sulfur in disulfides is not sufficiently different from that of thiols

    • The difference in currents between the two junctions is due to different contact areas between the mercury drop and the monolayer surface i.e, in this case the contact area for the n-Si-C12H25/Hg junction is considerably smaller than that for the n-Si-C11H22-S-Hg junction, The contact area could not be determined accurately in the set-up for temperature-dependent I-V measurements such that the current density could not be determined
