Abstract: Dynamic thermogravimetry (TG) analysis for thermal degradation kinetics were applied for amorphous carbon (a-C) thin films prepared by direct-current (DC) magnetron sputtering. The degradations generally consist release of free-bonded and weakly-bonded amorphous compositions and dissociation of highly-bonded compositions of higher graphitic orders. Using deconvolution technique for differential TG (DTG) curves, the apparent activation energy (E a) values for these stages were obtained, which were about 101-121, 117-121, 130-144 kJ mol -1. Structure characterizations before and during decompositions were analyzed and interpreted using X-ray photoelectron spectroscopy (XPS), Raman spectroscopy and evolution analysis. © 2005 Akadémiai Kiadó, Budapest.
