Summary: The study focuses on in-line graphene characterization on transparent substrates to determine quality, layer number, and area coverage, crucial for large-scale commercial production. A spatially resolved optical transmission technique combined with statistical analysis is used to map graphene layer number on different transparent substrates, without the need for user-inputted threshold values. The method can effectively map >1 cm(2) areas at 10 micron resolution and is applicable to a variety of transparent substrates.

Summary: Metal-supported few-layer graphene (FLG) was synthesized through microwave-assisted catalytic graphitization by converting bituminous coal to FLG over Fe catalysts at 1300 degrees C, resulting in the highest degree of graphitization and a well-developed pore structure. The microwave-irradiation temperature and holding time played critical roles in the synthesis of metal-supported FLG, with 3-6 layers of graphene nanosheets observed in the fabricated samples. Additionally, the presence of few-layer graphene structure was confirmed through the observation of the 2D Raman band at 2700 cm(-1).

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: Wrinkles significantly influence the thermal transport in vertical assemblies of few-layer graphene crystallites. While the presence of wrinkles enhances the thermal conductivity locally, it also leads to a significant decrease in the total interface conductance compared to unwrinkled regions. This study highlights the strong impact of wrinkles on the thermal properties of layered 2D materials.
