Epitaxial graphene films have been prepared by pulsed laser deposition. X-ray photoelectron spectroscopy analysis shows that the carbon binding energy is 284.7 eV, corresponding to sp2-C. Raman spectroscopy indicates that there exists 2D and D peaks and thus graphene structures have been formed. Meanwhile, according to high-resolution transmission electron microscopy analysis, suitable depositing...
In this work, we report an efficient method of chemical vapour deposition, without use of any metal catalysts, for the successful synthesis of vertical graphene nanoflake films (GNFs) on Si substrate. Effects of the growth condition on the surface morphology, microstructure, and chemical composition of GNFs are characterized by using scanning electron microscopy, transmission electron microscopy,...
Summary form only given. Amorphous hydrogenated carbon (a-C:H) films provide low friction, extreme hardness, chemically inertness, and good biocompatibility. a-C:H films have been expected a surface modification coating to medical appliances. However, poor adhesion of a-C:H film onto medical instruments which is metallic material limits their application. In order to improve the adhesion, the most...
Non-hydrogenated high sp3 content diamond-like carbon (DLC) has been subjected to intensive research efforts over the last three decades owing to its superior material properties. By introducing some metals/dopants into DLC film during deposition, the microstructure and properties of the films can be further modified, where studies have demonstrated it as an effective method to reduce the internal...
A challenge in exploiting the electrical properties of graphene is the fabrication of large area thin films in a scalable and inexpensive manner. The lack of a reliable and simple graphite exfoliation procedure has hindered the possibility of making films starting from pure graphene. This paper presents a scalable manner to obtain films of pure graphene on virtually any substrate with reproducible...
We investigate C60, C60(OH)24, C60(F3)12, C60Cl2 and analyse the stability of these derivatives upon processing in sol-gel, spin-coating, spraying, dropping and evaporating procedures to obtain thin films for possible microsystems application. We use X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, Near Edge X-ray Absorption Fine Structure...
