Turning many-body problems to few-body ones in photoexcited semiconductors using the stochastic variational method in momentum space, SVM-k
Dinh Van Tuan, Hanan Dery
We develop an efficient computational technique to calculate composite excitonic states in photoexcited semiconductors through the stochastic variational method (SVM). Many-body in…
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…
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…
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…
Intrinsic Spin Lifetime of Conduction Electrons in Germanium
Pengke Li, Yang Song, Hanan Dery
We investigate the intrinsic spin relaxation of conduction electrons in germanium due to electron-phonon scattering. We derive intravalley and intervalley spin-flip matrix elements…
