Properties of Ultra Fast Deposited Diamond-Like Hydrogenated Carbon Films

Diamond-like Carbon Films Deposited by Hydrocarbon Plasma Sources

Diamond-like carbon deposition techniques, characterization techniques and processing parameters, such as gas ratio, bias voltage, gas pressure, type of precursor gas used, temperature, gas total flow, substrate material, among others are reviewed. Mostly silicon substrates have been employed, but also metallic materials such as titanium and aluminum alloys or steels have been used as well. Imp...

Measuring the thickness of ultra-thin diamond-like carbon films

This paper examines the challenge posed by the measurement of thickness of sub-50 nm diamond-like carbon (DLC) films deposited onto silicon substrates. We compared contact profilometry (CP), optical profilometry (OP), contact atomic force microscopy (CAFM), tapping atomic force microscopy (TAFM) and X-ray reflectometry (XRR). Generally, CP, CAFM, TAFM and XRR give similar thickness values excep...

Deposition and characterization of ultra thin diamond like carbon films

Amorphous hydrogenated and/or nitrogenated carbon films, a-C:H/a-C:N, in overall thickness up to 2 nm are materials of choice as a mechanical and corrosion protection layer of the magnetic media in modern hard disk drive disks. In order to obtain high density and void-free films the sputtering technology has been replaced by different plasma and ion beam deposition techniques. Hydrocarbon gas p...

Antimicrobial Properties of Diamond-Like Carbon/Silver Nanocomposite Thin Films Deposited on Textiles: Towards Smart Bandages

In the current work, a new antibacterial bandage was proposed where diamond-like carbon with silver nanoparticle (DLC:Ag)-coated synthetic silk tissue was used as a building block. The DLC:Ag structure, the dimensions of nanoparticles, the silver concentration and the silver ion release were studied systematically employing scanning electron microscopy, energy dispersive X-ray spectroscopy and ...
