Oscillatory persistent currents in self-assembled quantum rings (2007)
Fomin, V.M., Gladilin, V.N., Granados, Daniel, Taboada, A.G., ...
We report the direct measurement of the persistent current carried by a single electron by means of magnetization experiments on self-assembled InAs/GaAs quantum rings. We measured the first...
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...
Alén, Benito, Bosch, J., Martínez-Pastor, Juan, Granados, Daniel, García, J.M., González, Luisa
We have carried out continuous wave and time resolved photoluminescence experiments in self-assembled In(Ga)As quantum dots and quantum rings embedded in field effect structure devices. In both kinds...
Ouerghui, W., Martínez-Pastor, J., Gomis, J., Melliti, A., Maaref, M.A., Granados, Daniel, ...
We present results concerning the carrier transfer between In(Ga)As quantum rings in a stacked multilayer structure, which is characterised by a bimodal size distribution. This transfer of carriers...
Continuum and discrete excitation spectrum of single quantum rings (2005)
Alén, Benito, Martínez-Pastor, Juan, Granados, Daniel, García, Jorge M.
Photoluminescence and excitation of the photoluminescence spectroscopy has been performed in single InGaAs self-assembled quantum rings embedded in a field effect structure device. To determine their...
