Web25 aug. 2005 · In this study, deposition of Au particles on HOPG substrates was performed by the conventional sputter coater (JEOL JFC-1500). The HOPG fabricated by NT-MDT was used in this experiment. The quality of HOPG was ZYB grade and the mosaic spread <0.8 ± 0.2°. HOPG substrates were cleaved with an adhesive tape in air prior to sputter coating … Web9 okt. 2024 · It was found that DPTTA molecules cannot form 2D self-assembled structures on a HOPG substrate. The reason for the different configurations of DPTTA/Au and DPTTA/HOPG systems was successfully revealed by the calculations of adsorption energy, weak interaction energy and electron density differences.
HOPG Substrates – Highly Ordered Pyrolytic Graphite
Webin most STM investigations HOPG is used as a simple substrate and the typical scan size is limited to 5 10 X 10 nm. Recognition of the different types of structures that can be present on freshly cleaved HOPG is important in distinguishing these from actual structures produced by species placed on an HOPG substrate and imaged by STM. Web25 feb. 2010 · By combining various complementary techniques including scanning tunneling microscopy, atomic force microscopy, x-ray diffraction, thermal desorption spectroscopy, and x-ray absorption spectroscopy the molecular orientation, crystalline structure, and morphology of the films as well as their thermal stability have been … convert sql to wql sccm
Structural and Nanotribological Properties of a BODIPY Self-Assembly
Web21 jul. 2014 · A density functional theory study of a cobalt(II) octaethylporphyrin (CoOEP) monolayer on Au(111) and HOPG(0001) surfaces was performed under periodic boundary conditions. Calculations with and without dispersion corrections are performed and the effect of van der Waals forces on the interface prope … Web8 apr. 2024 · Abstract. Polymorphic phases and collective phenomena—such as charge density waves (CDWs)—in transition metal dichalcogenides (TMDs) dictate the physical and electronic properties of the material. Most TMDs naturally occur in a single given phase, but the fine-tuning of growth conditions via methods such as molecular beam epitaxy (MBE ... convert sql to snowflake online
