As discussed above, we have achieved large-area, high-quality, fold-free graphene films in a temperature range between 1,000 K and 1,030 K. For the results that follow, we grew the fold-free film at an intermediate temperature of 1,020 K and studied the structure of the film in more detail. Homogeneous contrast over … See more In a previous study on adlayer-free graphene grown on home-made Cu(111) foils, centimetre-long parallel folds with widths of 80–100 nm and separated by 20–50 μm were observed (Supplementary Fig. 1)7. Ripples that … See more We found that the interfacial compressive stress induced by the shrinkage of the Cu–Ni(111) foil substrate from the growth temperature down to 1,030 K was entirely released by the formation of folds. It is the sudden formation of … See more Large-area, adlayer-free, single-layer graphene (SLG) films were formed on Cu–Ni(111) alloy foils (Supplementary Fig. 8) with a Ni … See more Graphene field effect transistor (GFET) devices were used to evaluate the electronic transport of the films. It has been reported that graphene films grown at high temperature … See more WebDec 30, 2024 · Graphene-reinforced metal/alloy matrix composites manifest excellent mechanical, thermal, and electrical properties.
