In CVD diamond growth, what are the growth sectors called?

Explanation:
Terraces and risers describe the stepped surface morphology seen as diamond grows in a CVD process. Growth occurs layer by layer, so flat areas on the surface—the terraces—are separated by steps, which form the risers. This step-flow growth creates a terraced surface and is the standard way to refer to the growth sectors observed during CVD diamond formation. Other terms like layers and sheets, crystals and boundaries, or faces and edges don’t capture this characteristic terraced, step-like structure of the growing surface.
