چکیده

Filmes finos de carbono amorfo hidrogenado (a-C:H) têm sido depositados na superfície de materiais para melhorar propriedades mecânicas, ópticas e químicas. Nesse estudo, foi empregado o sistema de deposição química assistida por plasma (PECVD) para sintetizar filmes de a-C:H com fases DLC (tipo diamante) e PLC (tipo polimérico). As pressões parciais de acetileno em argônio foram variadas e as estruturas dos produtos analisadas pela técnica de espectroscopia de reflexãoabsorção no infravermelho (IRRAS) e Raman. Além disso, a morfologia e as espessuras dos filmes foram determinadas por microscopia de força atômica (AFM) e perfilometria, respectivamente.

Effect Of Bipolar Pulsed Voltage On Properties Of DLC Films Deposited By Inductively Coupled PECVD

Diamond-like carbon (DLC) is a metastable form of amorphous carbon having large sp 3 bonding. DLC films have unique properties such as high hardness, low-friction, good transparency in IR region, chemical inertness and biocompatibility. To have better performance of the coating one should have proper selection of different parameters for deposition. In the present study, DLC films were deposite...

Thick DLC Films Deposited By PECVD on the Internal Surface of Cylindrical Substrates

A new and exciting technique for performing DLC deposition on the inside of cylindrical substrates, in particular pipes, will be described. Using the hollow cathode effect (HCE), a high density plasma can be generated within such cylindrical substrates by using Plasma Enhanced Chemical Vapor Deposition (PECVD). As the pipe itself is the vacuum chamber, such high density plasmas can be maintaine...

Nanofabrication of Diamond-like Carbon Templates for Nanoimprint Lithography

Diamond like carbon (DLC) films were deposited on Si and then patterned to form 40 nm features as nanoimprint templates. A plasma enhanced chemical vapor deposition (PECVD) system with CH4 precursor was used to deposit DLC films on Si and quartz substrates. These films were then characterized using Raman spectroscopy, atomic force microscopy (AFM), nanoindentation, and contact angle measurement...

Effect of growth time on ZnO thin films prepared by low temperature chemical bath deposition on PS substrate

ZnO thin films were successfully synthesized on a porous silicon (PS) substrate by chemical bathdeposition method. X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM),and photoluminescence (PL) analyses were carried out to investigate the effect of growth duration(3, 4, 5, and 6 h) on the optical and structural properties of the aligned ZnO nanorods. T...
