| 内容記述 | Irradiation-induced lattice defects in silicon carbide (SiC) are regarded as promising candidates for a multitude of quantum-information applications and quantum sensing. One of the most crucial parameters of any quantum system is the quantum coherence for the defects. By using the pulsed optically detected magnetic resonance (ODMR) technique, we investigate the spin-lattice relaxation time (T1) and spin-coherence time (T2) of silicon vacancies in 4H-SiC created by neutron, electron, and proton irradiation in a broad range of fluences. In addition, we investigated the effect of irradiation energy and sample annealing. We establish a robustness of the T1 time against all types of irradiation and reveal a universal scaling of the T2 time with the emitter density. Our results can be used to optimize the coherence properties of silicon-vacancy qubits in SiC for specific tasks. |
