Abstract

Substrate temperature during deposition of hard carbon films by short pulse (40 nsec, FWHM) eximer (308 nm) laser ablation (∼1.25 × 108 W/cm2) of solid carbon affects the optical and mechnical properties of deposited films. Films deposited at 25° C are superior to those deposited at 500° C. Deposited films were charaterized by spectroscopic ellipsometry, microhardness, TEM, Raman and FT-IR techniques.
