Abstract

Electron energy-loss spectroscopy (EELS) has been applied to the analysis of a-C:H films grown on various substrates by a unique low-temperature (> 100 °C) plasma-enhanced chemical vapor deposition (PECVD) process using ethylene and hydrogen gases. EELS data are used to characterize the relative amounts of fourfold coordinated sp3carbon bonding to threefold coordinated sp2carbon bonding as well as the relative order/disorder due to substrate effects. Ellipsometric and transmission measurements provide optical constants for the PECVD a-C:H films.
