Laser Micro-Raman Spectroscopy of CVD Nanocrystalline Diamond Thin Film
Laser micro-Raman spectroscopy is an ideal tool for assessment and characterization of various types of carbon-based materials. Due to its special optical properties (CrN) coated stainless steel substrates. NCD films have been investigated by laser micro-Raman spectroscopy. The fingerprint of diamond based materials is in the spectral region of 1000-1600 cm-1 in the first order of Raman scatter...
متن کاملElectrochemical preparation of peroxodisulfuric acid using boron doped diamond thin film electrodes
We have investigated the electrochemical oxidation of sulfuric acid on boron-doped synthetic diamond electrodes (BDD) obtained by HF CVD on p-Si. The results have shown that high current efficiency for sulfuric acid oxidation to peroxodisulfuric acid can be achieved in concentrated H2SO4 ( /2 M) at moderate temperatures (8 /10 8C). The main side reaction is oxygen evolution. Small amounts of pe...
متن کاملSpectroscopic Ellipsometry of Nanocrystalline Diamond Film Growth
With the retention of many of the unrivaled properties of bulk diamond but in thin-film form, nanocrystalline diamond (NCD) has applications ranging from micro-/nano-electromechanical systems to tribological coatings. However, with Young’s modulus, transparency, and thermal conductivity of films all dependent on the grain size and nondiamond content, compositional and structural analysis of the...
متن کاملChemical mechanical polishing of thin film diamond
The demonstration that Nanocrystalline Diamond (NCD) can retain the superior Young’s modulus (1100 GPa) of single crystal diamond twinned with its ability to be grown at low temperatures (<450 C) has driven a revival into the growth and applications of NCD thin films. However, owing to the competitive growth of crystals the resulting film has a roughness that evolves with film thickness, preven...
متن کاملAn Investigation on Two Types of Crystalline Micro-diamond Film Coated Tools Lapping with Sapphire Wafer
Two types of micron-diamond films were prepared on YG6 substrate by hot filament chemical vapor deposition(HFCVD) method. Morphology and orientation of crystalline growth were evaluated by SEM and XRD. Diamond film coated tools and sapphire wafer’ surface before and after lapping experiment were contrasted. The results indicated that a significant change in Raman spectrum of two types of micro...
