Radio-frequency glow-discharge films were deposited on various substrates starting with tetramethyltin and monobutyltrivinyltin. The films obtained were amorphous and contain C, H, and Sn. The C/Sn ratio as determined by ESCA varies with the reactor parameters. C-enriched films are found to be usually transparent, whereas Sn-enriched films are metallic in appearance and are conductors. There is no apparent difference in the structure of the transparent and metallic films. The conductivity, composition, and adhesion, and surface morphology are reported. The findings favor the mechanism of the film-forming process as due to atomic polymerization.
