Abstract
Provided are a diamond composite body capable of shortening a separation time for separating a substrate and a diamond layer, the substrate, and a method for manufacturing a diamond, as well as a diamond obtained from the diamond composite body and a tool including the diamond. The diamond composite body includes a substrate including a diamond seed crystal and having grooves in a main surface, a diamond layer formed on the main surface of the substrate, and a non-diamond layer formed on a substrate side at a constant depth from an interface between the substrate and the diamond layer.
Claims7
A diamond having a set of main surfaces, and including a line-shaped or lattice-shaped optical distortion when observed with light vertically passing through the set of main surfaces.
A diamond, comprising:
- a single crystal diamond layer having a set of main surfaces;
- and
- a layer containing implanted ions arranged on at least one of the main surfaces of the single crystal diamond layer,
- the layer containing implanted ions having line-shaped or lattice-shaped grooves penetrating to the single crystal diamond layer.
A diamond having a set of main surfaces, including a line-shaped or lattice-shaped array in mapping of intensities of photoluminescence (PL) and cathode luminescence (CL), or secondary electron intensity, reflected electron intensity, and absorbed current intensity in SEM, when observed from any one of the main surfaces.
