Electron Spin Resonance of P Donors in Isotopically Purified Si Detected by Contactless Photoconductivity

Philipp Ross, Brendon C. Rose, Cheuk C. Lo +4

Coherence times of electron spins bound to phosphorus donors have been measured, using a standard Hahn echo technique, to be up to 20 ms in isotopically pure silicon with [P]$ = 10…
