Exploiting of flux shadowing effect on InGaAs asymmetric shell growth for strain and bending engineering in GaAs - InGaAs core - shell NW arrays

Mahmoud Al Humaidi, Julian Jakob, Ali Al Hassan +8

Here we report on non-uniform shell growth of In(x)Ga(1-x)As onto GaAs nanowire (NW) core by molecular beam epitaxy (MBE). The growth was realized on pre-patterned silicon substrat…

In-situ X-ray analysis of misfit strain and curvature of bent polytypic GaAs-In(x)Ga(1-x)As core-shell nanowires

Mahmoud Al-Humaidi, Ludwig Feigl, Julian Jakob +9

Misfit strain in core-shell nanowires can be elastically released by nanowire bending in case of asymmetric shell growth around the nanowire core. In this work, we investigate the…

Beam damage of single semiconductor nanowires during X-ray nano beam diffraction experiments

Ali AlHassan, Jonas Lähnemann, Arman Davtyan +8

Nanoprobe X-ray diffraction (nXRD) using focused synchrotron radiation is a powerful technique to study the structural properties of individual semiconductor nanowires. However, wh…

Correlated nanoscale analysis of the emission from wurtzite versus zincblende (In,Ga)As/GaAs nanowire core-shell quantum wells

Jonas Lähnemann, Megan O. Hill, Jesús Herranz +12

While the properties of wurtzite GaAs have been extensively studied during the past decade, little is known about the influence of the crystal polytype on ternary (In,Ga)As quantum…

Norm minimized Scattering Data from Intensity Spectra

A. Seel, A. Davtyan, U. Pietsch +1

We apply the minimizing technique of compressive sensing (CS) to non-linear quadratic observations. For the example of coherent X-ray scattering we provide the formulae for a…
