Abstract
A single crystal CVD diamond component and a method of fabricating the single crystal CVD diamond component. The single crystal CVD diamond component comprises a surface, wherein at least a portion of the surface has been processed by chemical mechanical polishing, CMP, and a layer of quantum spin defects, said layer of quantum spin defects being disposed within 500 nm of the surface.
Claims20
A single crystal CVD diamond component comprising:
- a surface, wherein at least a portion of the surface has been processed by chemical mechanical polishing, CMP;
- a layer of quantum spin defects, said layer of quantum spin defects being disposed within 500 nm of the surface, wherein the chemical mechanical polishing of the surface reduces subsurface damage, which increases decoherence time, T2, of the quantum spin defects;
- and
- wherein the single crystal CVD diamond component has at least one lateral dimension of at least 0.5 mm.
