or electrostatic interactions. When alkanethiols are patterned on a gold substrate, a

monolayer is formed in which the thiol head groups form relatively strong bonds to

the gold and the alkane chains extend roughly perpendicular to the surface (Figure

1.9). Creating nanostructures using DPN is a single-step process that does not require

the use of resists. Using a conventional AFM, DPN has been reported to achieve

ultra-high resolution features with line widths as small as 10–15 nm with 5 nm

spatial resolution (Figure 1.10). For nanotechnological applications, it is not only

important to pattern ...
