High-quality paramagnetic defects in silicon carbide have been engineered by decoupling oxygen introduction from defect creation; this overcomes limitations imposed by previous methods reliant on ion implantation. This approach enables the formation of these defects deeper within the material and with greater uniformity than previously possible, improving both sensing capabilities and microscopic identification. Detailed analysis of hyperfine interactions across multiple samples conclusively identified PL6 defects as originating from an oxygen-vacancy complex.
A method to create stable flaws within silicon carbide has been developed that could improve the performance of quantum sensors; it involves carefully controlling the introduction of both oxygen and vacancies within the material’s structure. The technique allows for deeper and more consistent defect formation than previous methods relying on particle bombardment. Researchers at Kyoto University have devised a new technique to create stable flaws within silicon carbide that sharply enhances the performance of quantum sensors.
This involves carefully controlling both the introduction of oxygen and vacancies, microscopic missing...
