Electron nuclear double resonance with donor-bound excitons in silicon
Electron nuclear double resonance with donor-bound excitons in silicon
We present Auger-electron-detected magnetic resonance (AEDMR) experiments on phosphorus donors in silicon, where the selective optical generation of donor-bound excitons is used for the electrical detection of the electron spin state. Because of the long dephasing times of the electron spins in isotopically purified $^{28}\mathrm{Si}$, weak microwave fields are sufficient, …
