Enhancement of the optical and spin properties of silicon vacancies in proton-implanted 4H-SiC via femtosecond laser annealing

The silicon vacancy (VSi) in 4H-SiC represents a promising candidate for solid-state qubits. However, conventional high-temperature annealing typically suffers from undesired impurity diffusion and limited spatial localization during fabrication. Here, we present a femtosecond la...
