Abstract

The growth faces of large isolated chemical-vapour-deposited (CVD) diamond crystals have been studied using Raman microprobe spectroscopy. The crystals were grown on wire tips using microwave plasma chemical vapour deposition. This enables an effective study to be made of fundamental growth mechanisms by eliminating those defects and stresses associated with particle intergrowth in polycrystalline diamond thin films. A variation of the diamond line shape was observed from different growth directions of the same crystal. The [100] and [111] growth directions were sampled by focusing the laser spot onto the adjacent (100) and (111) growth faces of the same crystal. The high-resolution Raman sp..
