The surface morphology, microstructure, coating thickness, surface property, and electrical property of carbon coatings were investigated by optical microscopy, X-ray diffraction spectrometer, Raman scattering spectrometer, X-ray photoelectron spectrometer, field emission scanning electron microscopy, atomic force microscopy, contact angle meter, four point probe method, and nanoindenter. The results indicate that the deposition rate, surface roughness, and the electrical resistivity of the carbon coatings increase as the C2H2/(N2+C2H2) ratio, deposition temperature, deposition pressure increase or deposition flow rates decrease, while the degree of ordering, the mean crystallite size (Lc), in-plane crystallite size (La), water-repellency and mechanical properties of the carbon coating decrease. Additionally, based on the low-temperature surface morphology of the carbon coatings, the carbon coating deposited with coatings thickness greater than 289 nm is the best for use as the hermetical optical fiber coating. 薛顯宗 學位論文 ; thesis 124 zh-TW |
