Developments of Diamond-like Carbon Film for PET Bottles

Diamond-Like Carbon film from Liquid Gas on Metallic Substrates

Liquid gas was used to produce DLC films on Cu, Al and steel substrates by DC plasma technique. The absorption in IR reflectance indicates, grown films are DLC. By deconvolution of room temperature UVvisible spectra of the films grown at 50 mtorr and 200C, in addition to the spectra lines reported for CL, PL, PLC and ESR, some new spectra lines were obtained. We also, have seen exciton absorpti...

Effect of bias voltage on structural and mechanical characteristics of diamond-like carbon thin film applied by ion beam deposition

This study, investigates the effect of bias voltage on structural changes of diamond-like carbon thin film created by ion beam deposition is investigated. For this purpose, the bias voltage in the values of 0 V, -50 V, -100 V and -150 V on the AA5083 aluminum alloy was considered. Raman spectroscopy was used to evaluate structural. Influence of the bias voltage on the thickness and roughness of...

Diamond, Diamond-Like Carbon (DLC) and Diamond-Like Nanocomposite (DLN) Thin Films for MEMS Applications

Diamond-like carbon for magnetic storage disks

Diamond-like carbon films form a critical protective layer on magnetic hard disks and their reading heads. The ultimate limit to storage density is the super-paramagnetic limit, where the thermal energy is able to overcome the coercive energy of the magnetic bit. Perpendicular recording should allow storage densities up to ;1 Tbityinch . This requires the read head to approach 2 closer to the m...

Ultrathin diamond-like carbon film coated silver nanoparticles-based substrates for surface-enhanced Raman spectroscopy.

We have demonstrated that by coating with a thin dielectric layer of tetrahedral amorphous carbon (ta-C), a biocompatible and optical transparent material in the visible range, the Ag nanoparticle-based substrate becomes extremely suitable for surface-enhanced Raman spectroscopy (SERS). Our measurements show that a 10 A or thicker ta-C layer becomes efficient to protect the oxygen-free Ag in ai...
