SAMs are ordered molecular assemblies formed by the adsorption (qv) of an active surfactant on a solid surface (Fig. 6). This simple process makes SAMs inherently manufacturable and thus technologically attractive for building superlattices and for surface engineering. The order in these two-dimensional systems is produced by a spontaneous chemical synthesis at the interface, as the system approaches equilibrium. Although the area is not limited to long-chain molecules (112), SAMs of functionalized long-chain hydrocarbons are most frequently used as building blocks of supermolecular structures. 

Another interesting study describes the synthesis of large hexagonal close-packed Au NCSs from water-soluble mercaptosuccinic acid (MSA)-coated Au nanoparticles used as the building units. Au N Ps that form the superlattices can be interconnected by interpartide chemical bonding thanks to the mercaptosuccinic acid molecules over the Au nanoparticle surface [168] (Figure 3.15).

Silver has been reported to reduce the transformation temperature of FePt nanoparticles made by both sputtering and chemical synthesis [15, 16]. Furthermore, Ag, MgO and FePt have very similar lattice parameters (aAg = 0.40 nm) and therefore allows for a study of the transformation temperature without destroying the perpendicular texture. Here we describe the study of FePt/Ag multilayers deposited on MgO single crystal substrates at temperatures up to 400 °C. The X-ray diffraction patterns of the (FePt 2 nm/Ag 16 nm) pseudo-multilayers deposited on MgO [001] substrates at different temperatures are shown in Fig. 23. The superlattice (001) peak is present in all samples at temperatures above 280 °C, indicating the formation of Z,lo phase.
