摘要
The bondstructureofhydrogenated diamond likecarbon( DLC) filmsdeposited with plasmabased ionimplantation ( PBII) wascharacterized by Raman spectroscopy andcore level band and valenceband spectrum of XPS. Theresultsshow thatthe hydrogenated carbon filmspre pared with lower pulse bias, especially zero bias, display polymer like feature. The DLCfilms deposited with 15 kVpulsebiascontainsthehighestdensityofsp3 bonds. Thecore lev elband ( C1s) spectra of allfilmsshifttowardlow bindingenergy after4kVAr+ ion bom barding. The valenceband spectra of hydrogenated DLCfilmsarequite differentfrom thatof diamond and graphite. However, afterion bombarding, besidetwosingle peaksatabout17 0 eVand 12 5 eV(similarto graphite) ,two new sharp peaksappearatabout21 3 eVand 8 0 eV,respectively. Thepeak at8 0 eVcan beconsidertothecontribution duetothe actingofimplanted argon on C Cbondsand C Hbondsin thefilms.
