Sensor device formed of diamond material

Abstract

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.
