The carbon bonding ratio in diamond-like carbon (DLC) thin films has been estimated from the e2 spectra obtained by spectroscopic ellipsometry. A method has been developed to find out the atomic fractions of spand sp-bonded carbon atoms by combining the various features of the existing methods. The atomic fraction of sp-bonded carbon atoms has been determined by fitting the gaussian curves in t...

This paper comparatively studies the tribological behaviour of different types of diamond-like carbon (DLC) coatings in a reciprocating sliding wear test. The results are interpreted in terms of structure and surface morphological characteristics. At the beginning of each reciprocating sliding wear test, the higher coefficient of friction of the DLC coatings reflects the original surface condit...

Diamond-like carbon sDLCd films have always had high intrinsic stress due to their metastable structure and the fine balance between film density and bond stability. We show the effects of high intrinsic stress on the electron field emission performance, where a lower electric field for emission is recorded with increasing stress in the DLC films. In addition to examining “as deposited” films w...

The influence of the size carbon particles on parameters graphite–diamond phase transformation is considered. It shown that surface energy nanoparticles various shapes (spherical, columnar) makes a significant contribution to their total thermodynamic potential, which leads shift in diamond–graphite equilibrium curve low pressure region and an expansion diamond stability region. At same time, c...

The investigation of carbon allotropes such as graphite, diamond, fullerenes, nanotubes and carbon onions and mechanisms that underlie their mutual phase transformation is a long-standing problem of great fundamental importance. New diamond (n-diamond) is a novel metastable phase of carbon with a face-centered cubic structure; it is called "new diamond" because many reflections in its electron ...
