Here, within an atomistic pseudopotential theory, we offer recipes for the stimulated Raman adiabatic passage in embedded silicon and germanium nanocrystals. The transfer efficiency spectra display characteristic Fano resonances. By exploiting the Stark effect, we predict that transfer can be switched off with a dc voltage. As the population transfer is highly sensitive to structural variations, with a choice of a sufficiently small two-photon detuning bandwidth, it can be harnessed for addressing individual nanocrystals within an ensemble. © 2010 American Institute of Physics.EnglishAtomic systemCoherent population transferDC voltageDecoherenceFano resonancesGermanium nanocrystalsHighly sensitivePopulation transferPseudopotential theoryStimulated Raman adiabatic passageStructural variationsSwitchableTransfer efficiencyTwo-photon detuningGermaniumGround stateSpectroscopyNanocrystalsArticle10.1063/1.3526751
