Article Synopsis
- Traditional models of space-charge potentials focus on steady-state equilibrium, which doesn’t accurately reflect the behavior in wide band gap semiconductors with low defect concentrations.
- This study utilizes color centers in diamond to inject carriers into the crystal and observe how they behave under various potentials.
- The research reveals that by controlling the timing of carrier injection and the applied voltages, we can create and manipulate metastable charge patterns, demonstrating the potential for space-charge-induced carrier guidance.
We articulate confocal microscopy and electron spin resonance to implement spin-to-charge conversion in a small ensemble of nitrogen-vacancy (NV) centers in bulk diamond and demonstrate charge conversion of neighboring defects conditional on the NV spin state. We build on this observation to show time-resolved NV spin manipulation and ancilla-charge-aided NV spin state detection via integrated measurements. Our results hint at intriguing opportunities in the development of novel measurement strategies in fundamental science and quantum spintronics as well as in the search for enhanced forms of color-center-based metrology down to the limit of individual point defects.
