Computational modeling reveals active hydrocarbon species driving graphene growth on copper surfaces, suggesting strategies to optimize synthesis quality.

Key Points

Investigate the atomic-scale mechanisms and thermodynamic landscape governing graphene nucleation and growth on copper substrates during chemical vapor deposition.
Combined electronic structure calculations with molecular dynamics simulations.
Conducted thermodynamic analyses under typical experimental chemical vapor deposition conditions.
Isolated carbon atoms are thermodynamically unfavorable on copper surfaces under standard growth conditions.
Partially hydrogenated carbon radicals (CHx), rather than pure atomic carbon, serve as the primary active precursor species driving graphene growth and nucleation on copper.
