▎ 摘　　要

Pyrolytic carbon (PC) from ethanol was deposited on the carbon monofilaments by cold-wall chemical vapour deposition. Scanning electron microscopy (SEM) and Raman spectroscopy were employed to characterize the features of PC. An interesting appearance of Raman spectra was obtained for the PC deposition at 1000 square. The value of I-2700/I-G is about 2.23 and the feature is similar to that of the chemical vapour deposited graphene. It was concluded that the feature was induced by the regular microstructure of crystal grains with few defect in the sp(2) domains.
