Scientists Introduce Best Graphite Films to Date

Figure 2. (a) The mechanism of single crystalline graphite growth on a ultraflat single crystalline Ni foil: (i) carbon atoms of the solid carbon source dissolve into the single crystalline Ni; (ii) and the dissolved carbon atoms transport through the Ni foil to another side to forma graphene flakes; (iii) graphene flakes continuously merge into single crystalline graphene films and (iv) finally thick graphite films are formed on the single crystalline Ni substrate. (b) part of the experimentally grown inch-sized single crystalline graphite, on which the wrinkles formed during the cooling of the sample can be seen. (c) the ultra-flat graphite films formed by etching the substrate after growth. (Source: Unist) arrow back Image Zoom
