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 ...

Highly oriented pyrolytic graphite (HOPG) is a highly pure and ordered form of synthetic graphite. It is characterised by a low mosaic spread angle, meaning that the individual graphite crystallites are well aligned with each other. The best HOPG samples have mosaic spreads of less than 1 degree. Note … Meer weergeven The method used to produce HOPG is based on the process used to make pyrolytic graphite, but with additional tensile stress in the basal-plane direction. This produces improved alignment of the graphite … Meer weergeven HOPG is used in x-ray optics as a monochromator and in scanning probe microscopy as a substrate and for magnification … Meer weergeven WebSurface functionalization by oxidation was studied on the surface of highly oriented pyrolytic graphite (HOPG).
