“…Thin DLC films being transparent in the infrared region are resistant to IR-laser irradiation. This fact could be used to modify the film-substrate interface as it was shown in [187,188]. Irradiation by the first harmonics of a Nd:YAG laser (1.16 eV) stimulated formation of SiC and a slight hydrogenization of Si at the DLC-Si interface region.…”

In this work we present an overview on structure formation, optical and electrical properties of diamond like carbon (DLC) based metal nanocomposites deposited by reactive magnetron sputtering and treated by plasma and laser ablation methods. The influence of deposition mode and other technological conditions on the properties of the nanosized filler, matrix components and composition were studied systematically in relation to the final properties of the nanocomposites. Applications of the nanocomposites in the development of novel biosensors combining resonance response of wave guiding structures in DLC based nanocomposites as well as plasmonic effects are also presented.

“…These results are in agreement with the works of Kononenko et al [47] on laser-induced mechanisms in DLC films showing that the absorbed laser pulse produces an expansion of surface layer and reduces its mass density. Furthermore, Grigonis et al [5] demonstrated that the conversion of the sp 3 to sp 2 sites caused the swelling.…”

“…Amorphous carbon (a-C) is widely reported in the literature and used in many applications due to the large adaptability of its properties [1][2][3][4][5][6][7][8][9][10]. Its structure contains short range ordered domains mixing three hybridizations sp, sp 2 and sp 3 with different proportions of each them depending on deposition experimental parameters which in turn determines their properties.…”

Glassy carbon (GC) is a chemically stable form of fully sp 2-bonded carbon with locally ordered domains. GC is the intermediate material between graphite and diamond combining various properties such as high temperature resistance, hardness, good electrical conductivity, low density, low gases and liquids permeability and excellent resistance to a wide range of aggressive chemical environments. These characteristics make it a very promising material for many applications, but unfortunately it is not widely used because of the high temperatures required for its synthesis. In this work, synthesis of glassy carbon thin films by means of laser ablation of carbon targets under vacuum or in gaseous helium, followed by a nanosecond laser irradiation of the deposited films, is presented. In particular, it is demonstrated that the amorphous structure of a thin film can be efficiently modified to the one of glassy carbon film by nanosecond UV laser irradiation. This method is valuable to prepare thin films similar to commercial glassy carbon with a completely different route which does not require the application of temperature beyond 1000 o C which is not compatible with the silicon substrate for example. This opens for glassy carbon the way to microengineering applications (mechanics, electronics.. .). A particular attention is paid to characterize the vitreous carbon. In the literature, the vitreous nature of a carbon layers is often highlighted on the basis of Raman spectroscopy measurements. However, as the Raman spectrum of glassy carbon is similar to that of pyro-carbon, multiwall carbon nanotubes or functional graphene, this technique is not sufficient to safely characterize a carbonaceous material with a high degree of allotropy. To clear up any doubts, additional characterization methods, such as X-ray spectroscopy, transmission electron microscopy and Rutherford backscattering spectrometry, are discussed here.

“…The doped DLC fi lms are deposited by the same techniques as carbon fi lms (see Section 4.3), adding the doping-carrier species to the deposition environment (Grill, 1999). Other types of surface modifi cation, such as gas plasma treatments, infrared or ultraviolet irradiation by nanosecond laser, have also been used to change the surface properties of DLC fi lms (Mochizuki et al , 2011;Grigonis et al , 2011).…”
