Electron spin coherence of phosphorus donors in silicon: Effect of environmental nuclei
Electron spin coherence of phosphorus donors in silicon: Effect of environmental nuclei
Phosphorus-doped silicon single crystals with 0.19 % <= f <= 99.2 %, where f is the concentration of 29^Si isotopes, are measured at 8 K using a pulsed electron spin resonance technique, thereby the effect of environmental 29^Si nuclear spins on the donor electron spin is systematically studied. The linewidth …
