• surface. The self-assembled layers of CTAB molecules on the HOPG terraces prior to nanorod deposition were shown to change the wettability of the surface, and as a result, gold nanorod deposition takes place on nonwetting HOPG terraces. Keywords: CTAB; gold nanorods; micelles; self-assembly; wettability

• sections, it has been discussed in detail that the presence of CTAB molecules in a gold nanorod suspension will self-assemble all over the HOPG surface as shown in Figure 3, Figure 4, and Figure 5. Such deposition of CTAB layers on top of HOPG terraces will permit nanorods close to the three-phase contact

• plasma increases with decreasing gap distance between dimers down to a 4 nm gap, which was the smallest gap they examined. Boulais et al. [37] revealed the existence of two different physical regimes of plasma generation in the vicinity of a gold nanorod during ultrafast pulse exposure. For a fluence

• lower than 3 mJ/cm2, the gold nanorod strongly absorbed the incident pulse energy and the majority of the seed electrons were produced by photo-thermal emission (the absorption regime), while for fluences higher than 3 mJ/cm2 the formation of free electrons was dominated by multiphoton absorption due to

• a high near-field enhancement surrounding the gold nanorod (the near-field regime). At picosecond pulses with low irradiation fluence, nanoparticle-mediated LIB is dominated by photo-thermal emission due to the fast temperature increase of the electrons in the nanostructure.
