A method for manufacturing a device including a diamond crystal, the method including making available a substrate, growing a crystalline diamond layer on the substrate, the layer having a crystal lattice, the layer including at least a first set of XV centers in the crystal lattice, each XV center having a quantification axis, a main direction being defined for the first set, the quantification axes of the XV centers of the first set being parallel to the main direction, the normal direction being distinct from the main direction of the first set, removing a first part of the diamond layer in order to reveal a first face perpendicular to the main direction of the first set, and removing of a second part of the diamond layer in order to reveal a second face perpendicular to the first face.

Method for manufacturing a device comprising a diamond crystal

The invention relates to a device for the frequency analysis of a signal, comprising a diamond crystal having NV centers defining sub-regions, an excitation unit for optically or electrically exciting each sub-region, an injection unit for injecting a signal so that the sub-region is in the presence of the signal, a magnetic field generator designed so as to generate a magnetic field on each sub-region, the magnetic field having a spatial variation of amplitude in a first direction, and a detector for detecting the resonance frequency of each sub-region of the region, the detector comprising an electrical contact for detecting the charges created in a sub-region, and a reading circuit.
