Abstract

A thin plate of synthetic single crystal diamond material, the thin plate of synthetic single crystal diamond material having: a thickness in a range 100 nm to 50 μιη; a concentration of quantum spin defects greater than 0.1 ppb (parts-per-billion); a concentration of point defects other than the quantum spin defects of below 200 ppm (parts-per-million); and wherein at least one major face of the thin plate of synthetic single crystal diamond material comprises surface termination species which have zero nuclear spin and/or zero electron spin.
