Article Synopsis
- Transition-metal centers, specifically chromium (Cr) and manganese (Mn), show potential as paramagnetic spin defects in wide-bandgap semiconductors like AlN and GaN, making them valuable for applications in nanophotonics and quantum information processing.
- The study employs advanced hybrid density functional theory to analyze the electronic structure, stability, and optical properties of these centers, predicting their behavior and interactions under various conditions.
- Results indicate that these substitutional centers produce narrow quantum emissions around 1.2 eV, confirming their potential as effective spin qubits due to their favorable zero-field splitting parameters and proposed optical spin polarization methods.*
