Summary: Graphene/Cu composites show promise as future electrode materials due to their mechanical, electrical, and thermal stability. However, the presence of graphene accelerates oxidation of the underlying Cu surface, which affects the properties of the composites. Therefore, it is critical to investigate the effects of Cu oxidation on the interfacial properties of graphene/Cu composites.

Summary: This study investigates the charge distribution between layers in van der Waals stacked crystals using carbon isotope-labeled few-layer graphene. The electrical transfer characteristics of graphene field-effect transistors are used to calibrate the correspondence between Fermi level and G-phonon frequency. The results reveal that the charge concentration in both top and bottom layers of few-layer graphene is close and does not follow the exponential decay law. Additionally, each additional layer of graphene reduces the charge exchange at the graphene/dopant interface. These findings have important implications for electronic applications based on two-dimensional materials and provide a framework for further exploring the properties of other two-dimensional systems.

Summary: Graphene on hexagonal boron nitride (h-BN) demonstrates excellent electrical properties, which are affected by its domain size and boundaries. Chemical vapor deposition (CVD) is a hopeful method for large graphene crystal growth, but increasing the coverage of monolayer graphene on h-BN remains a challenge due to weak control of nucleation and vertical growth. In this study, an auxiliary source strategy using silicon carbide and methyl methacrylate is adopted to enhance graphene nucleation density and achieve continuous graphene films on h-BN. By optimizing the growth temperature, vertical accumulation of graphitic materials can be suppressed. This work provides an effective approach for preparing continuous graphene film on h-BN and offers insights for the growth of high-quality graphene.

Summary: An array of embedded graphene ribbons, connected to a buffer layer, can be grown on 4H-SiC(0001). The polarization dependence of the Raman D peak intensity at the armchair edge of the ribbon is similar to that of non-connected graphene armchair edges. The polarization dependence suggests that electrons and holes in the embedded graphene are scattered back at the boundary of the embedded graphene ribbon and buffer layer.

Summary: We investigate the structural changes in Si islands deposited on epitaxial few-layer graphene on SiC(0001) at room temperature during subsequent annealing. Annealing causes the movement of Si islands on thick epitaxial graphene and leaves behind monolayer-deep trenches. In contrast, Si islands do not form trenches on monolayer graphene, but instead intercalate to form quasifreestanding bilayer graphene. The termination of island motion results in SiC islands. Si islands are carbonized into SiC islands during annealing by incorporating carbon atoms from graphene, leading to the etching of graphene. The carbonization reaction of Si is the driving force behind the motion of Si islands.

Summary: We studied the mechanism of polytetrafluoroethylene (PTFE) chain scission using in situ hard X-ray photoelectron spectroscopy. The C-C bonds in the main chain and C-F bonds in the side chains were broken, resulting in F desorption from the PTFE surface. Recombination of broken C-C bonds and detached F led to the formation of CF3. The presence of thermal assistance at 230°C enhanced the formation of CF3 via recombination reactions. These findings have implications for the use of X-ray-irradiated fluorine resins and PTFE in space-based environments.

Summary: The origin of growth direction difference in graphene/hexagonal boron nitride (hBN) heterostructures during chemical vapor deposition (CVD) is theoretically studied. The study focuses on the energy gain with H termination of the bare hBN N edge on the Cu(111) surface compared to the bare graphene edge. The results indicate that the van der Waals correction method greatly affects the differences observed, and the most reliable method supports the speculation that the edge termination of existing islands automatically changes depending on whether it is graphene or hBN.

The breaking of C-F bonds in side chains and the observation of C-C bonds in the main chain were observed only on the surface under bending stress. The breaking of C-F bonds was found to be dependent on the tensile strain caused by bending.

Summary: By using core-level photoelectron spectroscopy, the surface of SiC(0001)-6 root 3 x 6 root 3R30 degrees (buffer layer surface) formed on n-type and semi-insulating substrates was studied. The adsorption of hydrocarbons and chemical bonding of oxygen atoms to the carbon atoms in the buffer layer were observed when the surface was exposed to air after buffer layer formation. However, annealing in ultra-high vacuum and an ethylene ambient resulted in the removal of these impurities and a clean buffer layer surface was obtained. The band bending of the buffer layer on the n-type and semi-insulating substrates was estimated through the peak position of Si 2p.
