Abstract

The local carbon-carbon bonding in evaporated (e-C) and ion-sputtered (i-C) amorphous carbon has been investigated by transmission electron-energy-loss spectroscopy (EELS) and by (e, 2e) spectroscopy. The EELS data indicate that the e-C is graphiclike and the i-C is diamondlike. The (e, 2e) data demonstrate that the concentration of sp2 bonding is ∼100% in both materials (0.85≤csp2≤1.0) for e-C and 0.75≤csp2≤1.0 for i-C). There is significant rehybridization of the π orbital in i-C.
