Silicon carbide formation by annealing C films on silicon

2013-5-8 · Silicon carbide films were grown on ~100! silicon substrates by deposition of 200-nm-thick C60 films, followed by annealing. The predeposited C60 is progressively destroyed by annealing, and carbon reacts with silicon to produce SiC. The reaction starts at the interface and continues by diffusion of silicon through the already formed SiC.
