This work, led by Mark Ku from the University of Delaware, showcases a diamond micro-chip (DMC) featuring a (111)-oriented nitrogen-vacancy (NV) center ensemble that enables high-resolution quantum microscopy of electrical current, magnetization, and spin structures. The diamond micro-chip was provided by the Qnami Quantum Foundry. Researchers demonstrate that the DMC exhibits minimal strain variation across large fields of view and maintains excellent NV spin coherence and optical quality—key for sensitive magnetometry. Using this platform, they achieve diffraction-limited, wide-field quantum microscopy of electrical currents and introduce a polymer-based method for deterministic DMC placement on various materials. These advances highlight the DMC’s potential to expand NV quantum sensing applications across materials science, electronics, spintronics, geology, biomedicine, and chemistry.
