Fabrication of an InGaAs spin filter by implantation of paramagnetic centers
C. T. Nguyen, A. Balocchi, D. Lagarde +6
We report on the selective creation of spin filltering regions in non-magnetic InGaAs layers by implantation of Ga ions by Focused Ion Beam. We demonstrate by photoluminescence spe…

Temperature insensitive optical alignment of the exciton in nanowire embedded GaN Quantum Dots
A. Balocchi, J. Renard, C. T. Nguyen +6
We report on the exciton spin dynamics of nanowire embedded GaN/AlN Quantum Dots (QDs) investigated by time-resolved photoluminescence spectroscopy. Under a linearly polarized quas…
