Growth and characterization of radio‐frequency plasma deposited gold‐carbon composites

摘要: Gold‐hydrocarbon composite thin films with various metal volume fractions have been deposited by a combination of sputtering and plasma deposition in argon‐propane plasma. Partial pressure control optical spectroscopy the gas phase shown growth processes to be partially dependent on chemical reactions occurring substrate. The polymer matrix structure was analyzed several techniques found consist dense hydrocarbon density 1.7. For low fractions, spectra show that dielectric nature predominates while metallic governs absorption phenomenon for gold‐rich films. Electrical conductivity measurements revealed influence graphitic structures film just above fraction p=0.03, below which carbon‐carbon sp2 bonds are more predominant. Similarly percolation threshold has occur at about p=0.3 exponent is evaluated 1.55.
