Surface stabilization phenomena on flame-deposited diamond single crystals

Surface stabilization phenomena on flame-deposited diamond single crystals

The acetylene-oxygen combustion flame technique was applied to the homoepitaxial deposition of diamond single crystals on cylindrically shaped {111}, {001} and {110} type IIa natural diamond substrates. After deposition the specimen revealed surface stabilization phenomena like flat facets and curved bands for orientations corresponding to Miller indices {hhk}h < k in the (110) zones. The surfa...

Orientation dependent surface stabilization on flame deposited diamond single crystals

In this study a model for the orientation dependent surface stabilization of diamond grown from the vapour phase is presented. The model is based on a first order broken bond analysis of the diamond crystal with additional considerations about surface reconstruction by dimer formation. Due to the formation of dimers, surface stabilization is expected for orientations corresponding to Miller ind...

Morphological Characterization of Combustion Deposited Diamond Crystals and Films

Single crystals and polycrystalline diamond films of several thicknesses were deposited using oxygen/acetylene combustion flame technique. The substrate used was pure polycrystalline molybdenum subjected to mechanical polishing. Quality and microstructural characteristic of diamond produced were investigated using X-Ray diffraction, Raman Spectroscopy, Scanning and Transmission Electron Microsc...
