“…Au has been used as catalyst for the controlled growth of Si, SiO 2 or Si/SiO 2 coaxial nanowires, with the emphasis placed on the role of the annealing conditions and the thickness of the Au films [14][15][16][17][18]. In addition, the optical properties of nanostructured Au films fabricated by controlled dewetting on transparent substrates have been intensively studied towards exploiting localized surface plasmon resonances in sensing, for enhancing the efficiency of photovoltaic devices used in solar cells, anti-reflective coatings and other applications [19][20][21][22][23].…”

High temperature evaporation methods, such as the vapor-liquid-solid mechanism, have been exploited for the controlled growth of ZnO nanostructures on various substrates. While Au is the most frequently used catalyst for growing ZnO nanowires, its morphological features on the substrate, which determine the size and shape of the nanostructures grown, have not yet been methodically explored. In the current work, we investigated the details of the thermal dewetting of Au films into nanoparticles on Si substrates. Au films of various thicknesses ranging from 2 to 15 nm were annealed under slow and fast rates at various temperatures and the morphological details of the nanoparticles formed were investigated. The dependence of the mean particle size on the nominal film thickness is in fair agreement with theoretical predictions. The vapor-liquid-solid method was employed to investigate the role of the Au nanoparticles on the growth details of ZnO nanowires. The efficient and high throughput growth of ZnO nanowires, for a given growth time, is realized in cases of thin Au films, i.e. when the thickness is lower than 10 nm. Based on these experimental findings, a two-step mechanism is proposed to account for the growth of ZnO nanorods ending in ultrathin (∼30 nm), micron-long tips.

We demonstrate the application of the 1,3-dipolar cycloaddition (“click” reaction) to couple gold nanoparticles (Au NPs) functionalized with low densities of functional ligands. The ligand coverage on the citrate-stabilized Au NPs was adjusted by the ligand:Au surface atom ratio, while maintaining the colloidal stability of the Au NPs in aqueous solution. A procedure was developed to determine the driving forces governing the selectivity and reactivity of citrate-stabilized and ligand-functionalized Au NPs on patterned self-assembled monolayers. We observed selective and remarkably stable chemical bonding of the Au NPs to the complimentarily functionalized substrate areas, even when estimating that only 1–2 chemical bonds are formed between the particles and the substrate.
