SUMMARY

The discussion centers on the feasibility of using a silicon carbide (SiC) wafer with a monolayer of graphene as a template for growing rebar graphene. The user inquires whether single wall carbon nanotubes (CNTs) can bond to the graphene after spin-coating and annealing, or if they would decompose instead. Previous methods for growing rebar graphene typically utilize copper (Cu) foil, raising questions about the effectiveness of the SiC wafer approach. The consensus indicates that while challenges exist, the proposed method warrants further exploration.

PREREQUISITES
  • Understanding of silicon carbide (SiC) wafer properties
  • Knowledge of graphene growth techniques
  • Familiarity with single wall carbon nanotubes (CNTs)
  • Experience with annealing processes in material science
NEXT STEPS

  • Explore alternative substrates for graphene growth
  • Investigate the annealing conditions for CNTs on graphene
  • Study the properties and applications of rebar graphene
USEFUL FOR

Materials scientists, nanotechnology researchers, and engineers involved in graphene production and applications will benefit from this discussion.

Hi, If I had a silicon carbide wafer Si-face with a monolayer of graphene on it, then spin-coat it with single wall carbon Nano tubes (CNTs) onto the graphene and then annealed it, would the CNTs bond to the graphene under them? Or would they still partially unzip and decompose forming a sheet of Rebar Graphene on top of it? I've read reports on how to grow rebar graphene but they use Copper (Cu) foil to grow it onto. I'd like to use the SiC wafer with a monolayer graphene as a template for the rebar graphene to grow on, is it Possible?
Thank you for your time.

Thank you for your help. It even helped me find info I'd haven't even thought of.
