Figure 2From: Physical and electrical properties of graphene grown under different hydrogen flow in low pressure chemical vapor depositionIllustration of growth process of CVD graphene on Cu. At 950°C for 1, 5, 10, 15 min at constant 10 and 400 sccm H2 flow (a-i). Illustrative growth schematics: (i) incubation, (ii) nucleation formation, (iii) growth and segregation, (iv) coalescence process, and (v) formation of films.Back to article page
