Development of Crystallographic Texture and In-Grain Misorientation in CVD-Produced Single and Polycrystalline Diamond

Extensive bulk and micro-texture measurements are used to characterize single and polycrystalline diamond thin films of different film thicknesses produced using CVD. With increasing film thickness, texturing improves and in-grain misorientation drops. This is observed for both single and polycrystalline films. Improved texturing in polycrystalline diamond can be rationalized from growth selection/advantage, however explanation(s) on the in-grain misorientation development and its relationship with texturing, if any, remain pending
