Strain driven migration of In during the growth of InAs/GaAs quantum posts
D. Alonso-Álvarez, B. Alén, J. M. Ripalda +6
Using the mechano-optical stress sensor technique, we observe a counter-intuitive reduction of the compressive stress when InAs is deposited on GaAs (001) during growth of quantum…
Charge control in laterally coupled double quantum dots
G. Muñoz-Matutano, M. Royo, J. I. Climente +9
We investigate the electronic and optical properties of InAs double quantum dots grown on GaAs (001) and laterally aligned along the [110] crystal direction. The emission spectrum…
Electrical control of a laterally ordered InAs/InP quantum dash array
B. Alen, D. Fuster, I. Fernandez-Martinez +4
We have fabricated an array of closely spaced quantum dashes starting from a planar array of self-assembled semiconductor quantum wires. The array is embedded in a metallic nanogap…
Exciton Gas Compression and Metallic Condensation in a Single Semiconductor Quantum Wire
Benito Alen, David Fuster, Guillermo Munoz-Matutano +3
We study the metal-insulator transition in individual self-assembled quantum wires and report optical evidences of metallic liquid condensation at low temperatures. Firstly, we obs…
InAs/InP single quantum wire formation and emission at 1.5 microns
B. Alén, D. Fuster, Y. González +4
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 s…
