## Abstract The differential gain and linewidth enhancement factor (__Ξ±__ βfactor) of a new material system InGaAsN/GaAs is studied using the 10βband **__k__** Β· **__p__** Hamiltonian matrix. A selfβconsistent scheme which involves simultaneous solution of the SchrΓΆdinger and Poisson equations is a
## Abstract We report on optical orientation experiments in undoped GaAsN epilayers and InGaAsN quantum wells (QW), showing that a strong electron spin polarisation can persist at room temperature. We demonstrate that the spin dynamics in these dilute nitride structures is governed by a spinβdepend
