Fine structure splitting cancellation in highly asymmetric InAs/InP droplet epitaxy quantum dots
N. R. S. van Venrooij, A. R. da Cruz, R. S. R. Gajjella +3
We find the single exciton's fine structure splitting (FSS), which splits its degenerate ground state manifold into singlets, nearly vanishes in highly asymmetric quantum dots due…
An atomic scale study of Si-doped AlAs by cross-sectional scanning tunneling microscopy and density functional theory
D. Tjeertes, A. Vela, T. J. F. Verstijnen +6
Silicon (Si) donors in GaAs have been the topic of extensive studies since Si is the most common and well understood n-type dopant in III-V semiconductor devices and substrates. Th…
Probing embedded topological modes in bulk-like GeTe-SbTe heterostructures
Hisao Nakamura, Johannes Hofmann, Nobuki Inoue +5
The interface between topological and normal insulators hosts metallic states that appear due to the change in band topology. While these topological states at a surface, i.e., a t…
Absence of quantum-confined Stark effect in GaN quantum disks embedded in (Al,Ga)N nanowires grown by molecular beam epitaxy
C. Sinito, P. Corfdir, C. Pfüller +14
Several of the key issues of planar (Al,Ga)N-based deep-ultraviolet light emitting diodes could potentially be overcome by utilizing nanowire heterostructures, exhibiting high stru…
Ferromagnetic Mn doped InSb studied at the atomic scale by cross-sectional STM
S. J. C. Mauger, J. Bocquel, P. M. Koenraad +3
We present an atomically resolved study of metal-organic vapor epitaxy grown Mn doped InSb that is ferromagnetic at room-temperature. Both topographic and spectroscopic measurement…
Geometric and compositional influences on spin-orbit induced circulating currents in nanostructures
J. van Bree, A. Yu. Silov, P. M. Koenraad +1
Circulating orbital currents, originating from the spin-orbit interaction, are calculated for semiconductor nanostructures in the shape of spheres, disks, spherical shells and ring…
