Interface-engineering enhanced light emission from Si/Ge quantum dots
Si quantum dots (QDs) have a significant improvement in luminous efficiency compared with bulk Si, achieved by alleviating the forbiddance of no-phonon Γ – Γ radiative transition determined by the law of momentum conservation. Two divergent mechanisms have been proposed to account for the breakdown...
