| Abstract [eng] |
In the present study DLC films were deposited on crystalline silicon and quartz substrates from hydrocarbon gases (acetylene (C2H2) and methane (CH4)) by two methods: employing closed drift ion source and radio frequency plasma enhanced chemical vapour deposition (RF PECVD) technique. Optical properties of the formed films were analyzed employing UV/VIS/NIR spectroscopy. It was observed that in both deposition methods the lowest refractive index (at λ = 632.8 nm), which corresponds to the highest amount of bound hydrogen, is observed when energies per carbon atom are approximately 150 eV (300 eV ion beam energy in a closed drift ion source) and 160 eV (400 V bias voltage in RF PECVD). It is shown that depending on the deposition conditions the region of minimum reflection for the system DLC-crystalline silicon can be varied in a wide range. |
