High-rate electron beam evaporation was combined with a spotless arc for plasma-asssisted thin film deposition.
The spotless arc burns between two molten titanium electrodes.
TiOx layers were deposited at a very high deposition rate (approximately 50 to 100 nm/s).
Amorphous as well as anatase-form crystalline TiO2 layers were produced.
Transparent amorphous layers with a high refractive index (2.4) were produced.
