Statistical exchange-coupling errors and the practicality of scalable silicon donor qubits
Yang Song, S. Das Sarma
Recent experimental efforts have led to considerable interest in donor-based localized electron spins in Si as viable qubits for a scalable silicon quantum computer. With the use o…
Suppressing spin relaxation in silicon
Oleg Chalaev, Yang Song, Hanan Dery
Uniaxial compressive strain along the [001] direction strongly suppresses the spin relaxation in silicon. When the strain level is large enough so that electrons are redistributed…
Theoretical Details of Tunnel Magnetoresistance via inelastic hopping at regime
Yang Song
Detailed theoretical derivation is given for the tunnel magnetoresistance via phonon-assisted hopping through an impurity chain under small magnetic field and a large bias window.…
Donor-driven spin relaxation in multi-valley semiconductors
Yang Song, Oleg Chalaev, Hanan Dery
We present a theory for spin relaxation of electrons due to scattering off the central-cell potential of impurities in silicon. Taking into account the multivalley nature of the co…
Impurity-assisted tunneling magnetoresistance under weak magnetic field
Oihana Txoperena, Yang Song, Lan Qing +4
Injection of spins into semiconductors is essential for the integration of the spin functionality into conventional electronics. Insulating layers are often inserted between ferrom…
Exchange-driven magnetoresistance in silicon facilitated by electrical spin injection
Yuichiro Ando, Lan Qing, Yang Song +6
We use electrical spin injection to probe exchange interactions in phosphorus doped silicon (Si:P). The detection is enabled by a magnetoresistance effect that demonstrates the eff…
