Core-shell nanowire heterostructures form the basis for many innovative devices. When compound nanowire shells are grown by directional deposition techniques, the azimuthal position of the sources for the different constituents in the growth reactor, substrate rotation, and nanowire self-shadowing inevitably lead to sequential deposition. Here, we uncover for In0.15Ga0.85As/GaAs shell quantum wells grown by molecular beam epitaxy a drastic impact of this sequentiality on the luminescence…

Enhanced luminescence properties of InAs-InAsP core-shell nanowires.
These findings highlight that enhanced mid-infrared emission efficiencies with effective carrier confinement and suppression of nonradiative recombination are highly sensitive to the quality of the InAs-InAsP core-shell interface.
Coaxial multishell (In,Ga)As/GaAs nanowires for near-infrared emission on Si substrates.
GaAs-based nanowires are used as building blocks for the emission of light with micrometer wavelength that are monolithically integrated on Si substrates to demonstrate the great potential of this technology.

Anomalous Strain Relaxation in Core-Shell Nanowire Heterostructures via Simultaneous Coherent and Incoherent Growth.
This work uncovers a novel strain relaxation process in GaAs/InxGa1-xAs core-shell nanowires that is a direct result of the nanofaceted nature of these nanostructures.
Growth map for Ga-assisted growth of GaAs nanowires on Si(111) substrates by molecular beam epitaxy.
A growth map is presented that comprehensively describes all nanowire and parasitic growth morphologies and hence enables growth of nanowires samples in a predictive manner and indicates the combination of global Ga flux and growth temperature determines the total density of all objects, whereas the global As/Ga flux ratio independently determines the resultant sample morphology.
Diameter evolution of selective area grown Ga-assisted GaAs nanowires
Tapering of vapour-liquid-solid (VLS) grown nanowires (NWs) is a widespread phenomenon resulting from dynamics of the liquid droplet during growth anddirect vapour-solid (VS) growth on the sidewall.

This work introduces a crystal growth platform-based on 3D structuring of growth substrates-which enables synthesis of semiconductor nanowire hybrids with in situ patterned superconductor shells, thereby enabling full freedom in the choice of hybrid constituents.
