Claims

C1strongest claim

By measuring isotope-resolved 17O hyperfine interactions, we identify them as the four crystallographic configurations of oxygen-vacancy (OV) complexes. Remarkably, single OV centers account for over 90% of the total defect population and exhibit superior optical properties and spin coherence compared with defects created by conventional carbon or nitrogen implantation.

C2weakest assumption

The distinct optical and spin-resonance signatures plus the 17O hyperfine patterns uniquely correspond to the four OV configurations without significant overlap from other implantation-induced defects or complexes.

C3one line summary

Oxygen-ion implantation produces four identifiable oxygen-vacancy complexes in 4H-SiC that comprise over 90 percent of defects and exhibit superior room-temperature quantum properties.
