Measurement of the spin temperature of optically cooled nuclei and GaAs hyperfine constants in GaAs/AlGaAs quantum dots
E. A. Chekhovich, A. Ulhaq, E. Zallo +3
Deep cooling of electron and nuclear spins is equivalent to achieving polarization degrees close to 100% and is a key requirement in solid state quantum information technologies. W…
Localized surface plasmons selectively coupled to resonant light in tubular microcavities
Yin Yin, Shilong Li, Stefan Böttner +5
Vertical gold-nanogaps are created on microtubular cavities to explore the coupling between resonant light supported by the microcavities and surface plasmons localized at the nano…
Universal recovery of the bright-exciton level-degeneracy in quantum dots without structural symmetry
R. Trotta, E. Zallo, C. Ortix +5
The lack of structural symmetry which usually characterizes semiconductor quantum dots lifts the energetic degeneracy of the bright excitonic states and hampers severely their use…
Observation of spin-selective tunneling in SiGe nanocrystals
G. Katsaros, V. N. Golovach, P. Spathis +6
Spin-selective tunneling of holes in SiGe nanocrystals contacted by normal-metal leads is reported. The spin selectivity arises from an interplay of the orbital effect of the magne…
Hybrid superconductor-semiconductor devices made from self-assembled SiGe nanocrystals on silicon
G. Katsaros, P. Spathis, M. Stoffel +7
The epitaxial growth of germanium on silicon leads to the self-assembly of SiGe nanocrystals via a process that allows the size, composition and position of the nanocrystals to be…
Polarization fine-structure and enhanced single-photon emission of self-assembled lateral InGaAs quantum dot molecules embedded in a planar micro-cavity
C. Hermannstädter, M. Witzany, G. J. Beirne +8
Single lateral InGaAs quantum dot molecules have been embedded in a planar micro-cavity in order to increase the luminescence extraction efficiency. Using a combination of metal-or…
