Topological nanophononic states by band inversion
Martin Esmann, Fabrice Roland Lamberti, Pascale Senellart +6
Nanophononics is essential for the engineering of thermal transport in nanostructured electronic devices, it greatly facilitates the manipulation of mechanical resonators in the qu…
Nanomechanical resonators based on adiabatic periodicity-breaking in a superlattice
F. R. Lamberti, M. Esmann, A. Lemaitre +7
We propose a novel acoustic cavity design where we confine a mechanical mode by adiabatically changing the acoustic properties of a GaAs/AlAs superlattice. By means of high resolut…
Exchange interaction-driven dynamic nuclear polarization in Mn-doped InGaAs/GaAs quantum dots
O. Krebs, E. Baudin, A. Lemaître
We investigated optical spin orientation and dynamic nuclear polarization (DNP) in individual self-assembled InGaAs/GaAs quantum dots (QDs) doped by a single Mn atom, a magnetic im…
Anomalous Hanle Effect in Quantum Dots : Evidence for Strong Dynamical Nuclear Polarization in Transverse Magnetic Field
O. Krebs, P. Maletinsky, T. Amand +5
Hanle effect is ubiquitous in the study of spin-related phenomena and has been used to determine spin lifetime, precession and transport in semiconductors. Here, we report an exper…
Manipulating exciton fine-structure in quantum dots with a lateral electric field
B. D. Gerardot, S. Seidl, P. A. Dalgarno +8
The fine structure of the neutral exciton in a single self assembled InGaAs quantum dot is investigated under the effect of a lateral electric field. Stark shifts up to 1.5 meV, an…
Bistability of the Nuclear Polarisation created through optical pumping in InGaAs Quantum Dots
P. -F. Braun, B. Urbaszek, T. Amand +5
We show that optical pumping of electron spins in individual InGaAs quantum dots leads to strong nuclear polarisation that we measure via the Overhauser shift (OHS) in magneto-phot…
