Formation and emission properties of single InGaAs/GaAs quantum dots and pairs grown by droplet epitaxy

Trabajo presentado a la 30th International Conference on the Physics of Semiconductors, celebrada en Seul (Korea) del 25 al 30 de Julio de 2010.

InAs/InP single quantum wire formation and emission at 1.5 microns

Isolated InAs/InP self-assembled quantum wires have been grown using in situ accumulated stress measurements to adjust the optimal InAs thickness. Atomic force microscopy imaging shows highly asymmetric nanostructures with average length exceeding more than ten times their width. High resolution optical investigation of as-grown samples reveals strong photoluminescence from individual quantum wires at 1.5 microns. Additional sharp features are related to monolayer fluctuations of the two dimensional InAs layer present during the early stages of the quantum wire self-assembling process.
