• crucial for the topography. This is not unexpected, as the roughness must be dependent on the morphology of the mushrooms, in particular at the point of coalescence. In this context we note that deposition on Au/Si under slightly different conditions such as −0.7 V for 1 s and −0.25 V for 20 s for

• for these liquids, according to the theoretical background, must be lower than 90°. The H2/R ratio, appearing in the coefficient of proportionality in Equation 4, must be treated carefully as coalescence of nanotubes was observed. The coalescence manifested by a slight depression of the nanotube film

• intertube separation distance calculated from the nanotube density in the HACNT film is ~310 nm, whereas an average pore size (R) derived from the H2/R ratio (20 m) is ~50 nm. This is also a reflection of the coalescence behaviour. Addition of a conventional anionic surfactant, sodium dodecylbenzene sulfate

NPs have irregular shapes elongated in the substrate plane due to coalescence processes during the synthesis. The morphological changes induced by the laser irradiation as a

In conclusion, flash laser annealing is a method of choice to fabricate 10 to 15 nm size magnetic alloy NPs with spherical shape and low polydispersity (~20%). Indeed
