“… 29 This can be better appreciated in Figure S3 . Indeed, Koç et al showed by AFM imaging the existence of linear structures of ordered self-assembled SiO 2 nanoparticles on the basal plane of the HOPG, which were also deposited by drop casting and seem to follow HOPG Moiré superlattices, 30 , 31 i.e., which are known to reproduce the honeycomb structure of the HOPG basal plane and lead to the assembly of organic molecules into stripe-like shaped motifs. 32 This would confirm that the formation of such striped structures, templated by Moiré pattern, is a growth model that is promoted during the dewetting process of a drop-casted colloidal solution.…”

The development of nanoribbon-like structures is an effective strategy to harness the potential benefits of graphenic materials due to their excellent electrical properties, advantageous edge sites, rapid electron transport, and large specific area. Herein, parallel and connected magnetic nanostructured nanoribbons are obtained through the synthesis of reduced graphene oxide (rGO) using NiCl 2 as a precursor with potential applications in nascent electronic and magnetic devices. Several analytical techniques have been used for the thorough characterization of the modified surfaces. Atomic force microscopy (AFM) shows the characteristic topographical features of the nanoribbons. While X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and Raman spectroscopy provided information on the chemical state of Ni and graphene-like structures, magnetic force microscopy (MFM) and scanning Kelvin probe microscopy (SKPFM) confirmed the preferential concentration of Ni onto rGO nanoribbons. These results indicate that the synthesized material shows 1D ordering of nickel nanoparticles (NiNPs)-decorating tiny rGO flakes into thin threads and the subsequent 2D arrangement of the latter into parallel ribbons following the topography of the HOPG basal plane.

In this work, ZnO:TiO2 nanocomposites thin films were produced, and electrical properties were evaluated. Nanocomposite nanoparticles were used as thin film source in the preparation which was produced using sol-gel synthesis in different concentrations. Spin coating process was adopted in the preparation of ZnO:TiO2 nanocomposites films. In the thin film preparation pure TiO2, and nanocomposites in 1:5 ZnO:TiO2 and 1:2 ZnO:TiO2 concentrations were prepared. Electrical properties of the ZnO:TiO2 composites were assessed where capacitance-voltage and conductancevoltage measurements were performed. Adjusted conductance (Gadj)-voltage (V) and adjusted capacitance (Cadj)-voltage (V) characteristics were studied. Frequency dependent characteristics were obtained in the electrical measurements. The density of interface states (Dit) was assessed; results illustrated that the Dit has frequency dependent characteristics.

“…Then, samples can be investigated by high-resolution atomic force microscopy (AFM) in ambient conditions. For instance, ordered porous supramolecular networks on graphene and nanoscale stripe arrays on graphite have been obtained by using a drop-casting procedure [21,22]. Here, we successfully achieved the formation of large-scale 2D networks based on tailored OPPs using a very simple spin-coating procedure on a highly oriented pyrolytic graphite (HOPG) surface under ambient conditions.…”

The formation of functional networks on surfaces is one of the main challenges in the field of nanotechnologies. In this paper, we shall propose a very simple process which can be used to achieve the formation of extended monolayer of functional oligo(para-phenylenes) molecules at the air/graphite interface. By developing a convergent strategy, we successfully achieved the synthesis of oligo(para-phenylenes) molecules with a tuneable length. The photophysical properties of these new oligomers were characterized by UV-vis absorption and fluorescence spectroscopy. Deposition of these molecules by a simple spin-coating process on a highly oriented pyrolytic graphite (HOPG) surface leads to the formation of extended monolayered 2D networks. These networks were characterized by atomic force microscopy experiments under ambient conditions with submolecular resolution thus providing the adsorption model of these molecules on an HOPG surface.
