Effect of the GaAsP shell on optical properties of self-catalyzed GaAs nanowires grown on silicon
O. D. D. Couto, D. Sercombe, J. Puebla +9
We realize growth of self-catalyzed core-shell GaAs/GaAsP nanowires (NWs) on Si substrates using molecular-beam epitaxy. Transmission electron microscopy (TEM) of single GaAs/GaAsP…

Charge control in InP/GaInP single quantum dots embedded in Schottky diodes
O. D. D. Couto, J. Puebla, E. A. Chekhovich +6
We demonstrate control by applied electric field of the charge states in single self-assembled InP quantum dots placed in GaInP Schottky structures grown by metalorganic vapor phas…
