Fluorination effects on tribological characteristics of hydrogenated amorphous carbon thin films

Rubio-Roy M., Portal S., Polo M.C., Pascual E., Bertran E., Andújar J.L., Universitat de Barcelona, ES

Hydrogenated amorphous carbon (a C:H) films are good candidates for biomedical applications, requiring smooth surfaces, biocompatibility and singular tribological characteristics. The addition of elements to a C:H films, such as oxygen, silicon, fluorine or metals, [...]

Carbon nanostructures grown with electron and ion beam methods

Lemoine P., Roy S.S., Maguire P.D., McLaughlin J.A.D., University of Ulster, UK

Simultaneous deposition and patterning of carbon nanostructures can be performed using focused electron beams or ion beams. Although a variety of useful tri-dimensional structures have been prepared (single electron transistor, nanotools, AFM probes, etc.), the [...]

Structural Study of Amorphous Carbon using Adaptive Interatomic Reactive Empirical Bond-order Potential Model

Knippenberg M.T., Kum O., Stuart S.J., Clemson University, US

We studied the structural properties of amorphous carbon covering a wide range of densities from low-density to high-density regime using classical molecular dynamics with reactive empirical bond-order potential model. We calculated the pair-correlation functions, relative [...]

Metastable Site in Amorphous Carbon Lattice Generated by Rapid Quenching of Liquid Diamond

Lee J-G, Lee K-R, Lee K.H., Lee S-C, Lee S-H., Lee J-G, Lee K-R, Lee K.H., Lee S-C, Lee S-H., Lee J-G, Lee K-R, Lee K.H., Lee S-C, Lee S-H., Lee J-G, Lee K-R, Lee K.H., Lee S-C, Lee S-H., Lee J-G, Lee K-R, Lee K.H., Lee S-C, Lee S-H., Korea Institute of Science and Technology, KR

Formation of amorphous structure of carbon by rapid quenching of the liquid phase was investigated by molecular dynamic (MD) simulation using Tersoff’s empirical potential. Physical properties of crystalline diamond, such as lattice parameter, surface energy [...]
