I'm trying to sputter coat an experimental material with amorphous carbon, but I'm having serious adhesion issues. The film peels off in a matter of days, even with a 100 nm PECVD SiO2 capping. Is there anything I can use as a bonding layer?
Maybe you want to check this somewhat related discussion ― concerning to soot adhesion to glass: https://www.researchgate.net/post/Why_flame_synthesized_soot_is_more_stably_adhere_at_quartz_glass_than_amorphous_glass
QI: Thank you for the suggestion. Unfortunately I'm limited to room temperature sputtering of pure carbon alone, so no doping for me.
Interesting, thank you Carlos! Just to be sure, would a hydrophilic or hydrophobic coating work best? I have HMDS, sputtered silicon, PECVD SiO2 and in a pinch spin coated PMMA available.
