WebNov 1, 1992 · / An STM study of single-crystal graphite the W wire and the gold ring. The tip was washed in distilled water before use. Each sample is freshly cleaved before examination. An optically flat, shiny area of the surface is located under the tip by manually guiding the sample while observing through the optical microscope. After initial approach ... WebSep 2, 2024 · STM is a powerful tool to investigate correlated electron systems, for example, uncovering the inhomogeneities in the order parameter of high T C superconductors or nematicity in “magic angle” bilayer graphene (34–37).We present STM measurements at a temperature of 9.6 K, on the surface of SiO 2-supported RG ().At half filling of the flat …
Webof graphite, It is shown that the STM images display threefold sym- metry coming from the inequivalence of the two atoms in the surface layer of graphite, and vary depending on the size of the tip. 2.
