Patent number: 12234570Abstract: A method of forming a diamond composite body and the diamond composite body. A first single crystal diamond body is provided, which contains nitrogen and has a uniform strain such that over an area of at least 1×1 mm, at least 90 percent of points display a modulus of strain-induced shift of NV resonance of less than 200 kHz, wherein each point in the area is a resolved region of 50 ?m2. The first single crystal diamond body is treated to convert at least some of the nitrogen to form at least 0.3 ppm nitrogen-vacancy, NV?, centres.

Publication number: 20250052839Abstract: A sensor device formed of diamond material. The sensor device has a spin defect located in the diamond material, and an electrically conducting region located so as to be interactable with the spin defect. The electrically conducting region extends from an interior location of the diamond material to a surface of the diamond material. The electrically conducting region at the surface of the diamond material is arranged to connect to a detector, the detector configured to detect charge carriers excited from the at least one spin defect via the electrically conducting region. This allows the use of a higher volume of the diamond sensor than would be the case if one were limited to using spin defects close to the surface.Type: ApplicationFiled: December 19, 2022Publication date: February 13, 2025Inventors: Pierre-Olivier François Marc COLARD, Andrew Mark EDMONDS, Matthew Lee MARKHAM
