SYNTHETIC SINGLE-CRYSTAL DIAMOND AND MANUFACTURING METHOD THEREOF

A synthetic single crystal diamond containing nitrogen atoms at a concentration of 100 ppm or more and 1500 ppm or less based on atom numbers, in which the synthetic single crystal diamond contains aggregates each composed of one vacancy and three substitutional nitrogen atoms present adjacent to th...

Zusammenfassung:A synthetic single crystal diamond containing nitrogen atoms at a concentration of 100 ppm or more and 1500 ppm or less based on atom numbers, in which the synthetic single crystal diamond contains aggregates each composed of one vacancy and three substitutional nitrogen atoms present adjacent to the vacancy, and a Raman shift λ' cm-1 of a peak in a first-order Raman scattering spectrum of the synthetic single crystal diamond and a Raman shift λ cm-1 of a peak in a first-order Raman scattering spectrum of a synthetic type IIa single crystal diamond containing nitrogen atoms at a concentration of 1 ppm or less based on atom numbers show a relationship of the following formula 1, λ′−λ≥0
