SINGLE-CRYSTAL DIAMOND AND METHOD OF MANUFACTURING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18283803 titled 'SINGLE-CRYSTAL DIAMOND AND METHOD OF MANUFACTURING THE SAME
Simplified Explanation
The patent application describes a single-crystal diamond with specific characteristics, including a narrow X-ray diffraction rocking curve, a peak at a specific Raman shift with a narrow half-width, low etch-pit density, and a controlled nitrogen content.
- Narrow X-ray diffraction rocking curve:
- Half-width of 20 seconds or less - Measured with CuKα radiation in a (004) plane parallel arrangement - Utilizes a diamond crystal as the first crystal in X-ray diffraction by a double-crystal method
- Narrow peak at a specific Raman shift:
- Raman shift in the range of 1332 cm to 1333 cm - Half-width of 2.0 cm or less
- Low etch-pit density:
- 10,000/cm² or less - Measured in an etching test
- Controlled nitrogen content:
- More than 0.1 ppm and 50 ppm or less based on the number of atoms
