Determination of spin polarization in InAs/GaAs self-assembled quantum dots
F. G. G. Hernandez, T. P. Mayer Alegre, G. Medeiros-Ribeiro
The spin polarization of electrons trapped in InAs self-assembled quantum dot ensembles is investigated. A statistical approach for the population of the spin levels allows one to…
Alloying mechanisms for epitaxial nanocrystals
M. S. Leite, G. Medeiros-Ribeiro, T. I. Kamins +1
The different mechanisms involved in the alloying of epitaxial nanocrystals are reported in this letter. Intermixing during growth, surface diffusion and intra-island diffusion wer…
Atomic ordering in self-assembled Ge:Si(001) islands observed by X-ray scattering
A. Malachias, T. U. Schulli, G. Medeiros-Ribeiro +4
X-ray diffuse scattering in the vicinity of a basis-forbidden (200) Bragg reflection was measured for a sample with uncapped self-assembled Ge islands epitaxially grown on Si(001).…
