Finally, it must be stressed that X-ray microanalysis provides the mass thickness, and not the geometrical thickness, of the analysed .methods, and therefore tools to routinely characterise thin films are of the upmost importance to the thin film engineer/scientist. Fortunately, X-ray diffraction (XRD) provides such a tool, and is arguably the most useful and versatile technique in the characterisation of thin films.1 XRD can be used to obtain the following Figure 1. (A) Schematic illustration to form a polymer–precursor complex thin film and its conversion to a MoS 2 thin film on an SiO 2 /Si wafer. (B,C) Digital image and three-dimensional AFM image of the as-synthesized MoS 2 thin film on a 6-in. SiO 2 /Si wafer by spin-coating a 100 mM precursor solution.
