Dressed excitonic states and quantum interference in a three-level quantum dot ladder system (2008)
Gerardot, B. D., Brunner, D., Dalgarno, P. A., Karrai, K., Badolato, A., Petroff, P. M., ...
We observe dressed states and quantum interference effects in a strongly driven three-level quantum dot ladder system. The effect of a strong coupling field on one dipole transition is measured by a...
Dalgarno, P. A., Smith, J. M., McFarlane, J., Gerardot, B. D., Karrai, K., Badolato, A., ...
We present results on the charge dependence of the radiative recombination lifetime, Tau, and the emission energy of excitons confined to single self-assembled InGaAs quantum dots. There are...
Contrast in transmission spectroscopy of a single quantum dot (2007)
Gerardot, B. D., Seidl, S., Dalgarno, P. A., Kroner, M., Karrai, K., Badolato, A., ...
We perform transmission spectroscopy on single quantum dots and examine the effects of a resident carriers spin, the incident laser spot size, polarization, and power on the experimental contrast. We...
Manipulating exciton fine structure in quantum dots with a lateral electric field (2007)
Gerardot, B.D., Seidl, S., Dalgarno, P.A., Warburton, R.J., Granados, Daniel, García, J.M., ...
The fine structure of the neutral exciton in a single self-assembled InGaAs quantum dot is investigated under the effect of a lateral electric field. Stark shifts up to 1.5 meV, an increase in...
Manipulating exciton fine-structure in quantum dots with a lateral electric field (2006)
Gerardot, B. D., Seidl, S., Dalgarno, P. A., Warburton, R. J., Granados, D., Garcia, J. M., ...
The fine structure of the neutral exciton in a single self assembled InGaAs quantum dot is investigated under the effect of a lateral electric field. Stark shifts up to 1.5 meV, an increase in...
Power-law carrier dynamics in semiconductor nanocrystals at nanosecond time scales (2006)
Sher, P. H., Smith, J. M., Dalgarno, P. A., Warburton, R. J., Chen, X., Dobson, P. J., ...
We report the observation of power law dynamics on nanosecond to microsecond time scales in the fluorescence decay from semiconductor nanocrystals, and draw a comparison between this behavior and...
Seidl, S., Kroner, M., Dalgarno, P. A., Högele, A., Smith, J. M., Ediger, M., ...
We have performed detailed photoluminescence (PL) and absorption spectroscopy on the same single self-assembled quantum dot in a charge-tunable device. The transition from neutral to charged exciton...
