Abstract

DLC(Diamond-Like Carbon) films were prepared by Inductively Coupled Plasma(ICP) CVD system. It was confirmed that the field emission characteristics are closely related to the richness of C-H bonding incorporated in the DLC. According to Fowler-Nordheim equation, it is thought that the ability of DLC to emit electron at relatively low voltage is due to the field enhancement caused by the nodules of ${\sim}100nm$ size on the surface of DLC. The electric field to start field emission was about $1.4{\times}10^9V/m$ in case of DLC film deposited at input power of 400W and substrate bias of -100V.
