The nitrogen vacancy (NV) center in diamond is an increasingly popular quantum sensor for microscopy of electrical current, magnetization, and spins. However, efficient NV-sample integration with a robust, high-quality interface remains outstanding challenge to realize scalable, high-throughput microscopy. In this work, we characterize micro-chip (DMC) containing (111)-oriented NV ensemble; demonstrate its utility high-resolution We perform strain imaging the DMC find minimal detrimental variation across field-of-view tens micrometer. good ensemble spin coherence optical properties DMC, suitable sensitive magnetometry. then use wide-field show that diffraction-limited can be achieved. also deterministic transfer DMCs multiple materials interest next-generation electronics spintronics. Lastly, develop polymer-based technique placement. This work establishes DMC's potential expand application materials, device, geological, biomedical, chemical sciences.
